I was just given a brand new Remington 742 Woodsmaster 30.06 from the original owner, and I know NOTHING about this gun... but I am reading some mixed reviews on the net (with a grain of salt of course)

I say brand new but according the serial #s the gun is 31 years old. I have known the owner for 15 years and did not even know he had this gun in his safe until he gave it to me. He says... and I believe him... that 6 rounds total have been fired through this gun in 31 years. There is not a scratch on it, it looks as if it just came out of the original packaging. Bluing, stock, chamber, barrel, receiver etc... are all A#1 first class condition. At some point in its life it was dropped and the front sight is bent all to hades but that is replaceable.

So... I plan on replacing the front and rear sights with ghost rings and making this my pig gun, safari style...

Leather sling, a nice leather bullet carrier for the stock etc...

Anyone wanna tell me what I've got here? If you own or have owned one of these give me your do's and don'ts... Taking it to the range in a couple of weeks after I get my new sights...

They are great hunting rifles, but they are not made for a lot of shooting otherwise you will have problems. Make sure the chamber is clean and dry and shoot it like you stole it.

I've got a 742 in .243 that was my father's. It has jammed on me one time. I took it to my father in-law that was a gunsmith at the time and had him look it over. He gave it a good cleaning, and since then I always make sure I give it a good cleaning aftr each use. Keep it clean, and it should work fine. Yes there are problems, but many are attributed to magazine problems and/or cleanliness of the rifle.

Get some of those big (tipton) cotton swabs with wire handles they sell for cleaning. Make sure you clean and lube the chamber and inside of receiver each time you shoot it.

That, and make sure you don't pull the trigger if you have the trigger assembly part out of the rifle. :banghead:

Keep it clean & don't make it a range rifle. Sight it in and then only use it for hunting. They have a reputation for jamming once they've had a few hundred rounds put through them...a well earned reputation.

I have a 740 which is basically the same gun (the first of the series)

It is a good thing that it has not been used because the bolt rail in the receiver with time will get chewed up ad the rifle will start to jam...it is possible to repair them but highly antieconomical.

They are good semi-auto rifles...accurate for being an autoloader (generally even more than your usual semi-auto assault type 7,62 rifle like a CETME or FAL, etc...)

Keep the chamber very clean.....you can have fun at the range occasinally shooting a couple of boxes but they are not designed for intensive shooting.

A very good rifle for its intended purpose overall.

Remington keep producing them since 1955 so people must like them....

Sell it to someone else and buy another gun. Maybe buy a cheaper Garand from CMP in 30-06. It will function much better.

Ignoring the disparaging comments made by those whose only knowledge of the gun in question is what they have read on the internet, the 742 when properly cared for is an accurate and reliable piece of equipment.

I have not been able to wear mine out.

I have an older 740 from the early 1960's and it has been in hunting service every year since. The bolt rails are starting to get chewed up but it has not begun to jam yet. The 740's and 742's all have this problem. For some reason, the bolt carrier is built very loose and it "chatters" down the rails when you fire it causing a series of little dents on the rails. Mine happens to be chambered for .308 and I have been told by a gunsmith that I could reduce this by sticking to bullets of 150 grains or less. I don't know the wisdom of this advice and I have no experience with any other caliber. I do have a friend that has a 742 in 30-06 with the same chatter marks. I think as a result of a design flaw, these guns are destined to self destruct at some point. That said, mine has taken 48 years of annual sighting in and whitetail hunting to get to this point. I keep mine because it was purchased and hunted with by my dad before I was born and he passed it down to me as my first rifle. He passed away last month and left me with a relatively new condition 742 in 30-06. I am keeping it and putting it into service. These guns might not be passed down to our great grandchildren but they can be great accurate rifles for decades.

A very nice essay about the Remington 740/742 and 7400 with a detailed description of the decades long battle that Remington was engaged in resolving the "bolt rail battering" issue.

Overall, nice rifles, dependable, fairly accurate, light and nice looking.

However the 740 and 742 seems destined to become wall hangers one day if they shoot enough rounds (still many people had them in hunting services for years)
A gunsmith can shave and repolish the rails a couple of time but eventually there will be no metal left.

So, if you buy one used, be aware that the infamous problem may have already show up...you can easily inspect the rails (remove the magazine, keep the bolt back and inspect with a light)

The 7400 seems to have resolved the issue (Remington slowed the velocity of the action)....still there is a bit of rail battering but way less than before and, because the bolt has now only 3 large lugs instead of the small 15, the impact surface is large enough to do not create a ding.

If used for many several thousands of shots, probably even the 7400 may eventually develop problems but that kind of usege is unlikely for the averge shooter and for the purpose that rifle was designed for anyway.


======================================================

The American sportsman has historically not much used semi-automatic rifles for his hunting purposes, but there have been a few successful models that some hunters have put to such good use that the guns have become legends. In 1955, with the U.S. now flooded with men that had become fond of the M1 Garand's power and reliability during their service in WWII and in the Korean War (let's face facts, it WAS a "war"), Remington introduced the model 740. The 740 was an instant success for Remington. Named the "Woodsmaster," it offered top big-game rounds, dependability, semi-auto firepower, decent accuracy, and a sporting appearance. With its sleek lines, basket-weeve checkered walnut stock and deeply blued steel, it was a beauty that no doubt haunted many hunters' dreams. It was a little pricey compared to the more traditional bolt actions and lever actions, but many hunters managed to get their hands on a 740. Those first few hundred 740s out the door were likely the talk of the hunting camps, and as others began seeing the 740s prove dependable enough for their buddies, more hunters went to get their own.

The 740 was issued in .30-06 Springfield. This initial chambering was one contributing factor to the gun's early popularity as there has probably not been a more "standard" big-game round in use in America, and that round had already proven itself with America's servicemen for half a century by the time it was offered in the 740. Soon after the initial chambering was offered, the chamberings of the .244 Remington (6mm Remington), .308 Winchester and the .280 Remington (7mm Express) were also offered. The 740 offered a 4 round detacheable box magazine, and came equipped with adjustable iron sights and was drilled and tapped for a scope mount. Since the ejection port was on the right side, the scope mount could be attached directly over and in-line with the barrel which was an added benefit to the design.

The 740 design used a gas pulse to operate a piston located beneath the barrel in the hollowed forearm. The bolt head pivotted in its carrier and locked secure inside a barrel extension instead of the receiver which was revolutionary for its time. To aid in its fast cyclic rate, the bolt used smaller locking lugs than guns normally did, or do today. But, it had a total of 15 of these small lugs which actually gave the bolt's lock-up more strength than many bolt actions and certainly better than the lever actions of the period.

After only a few years, Remington was hearing of complaints regarding one particular area of the gun, however. The top inside of the receiver had a long built-in rail on which the bolt body rode during cycling. The speed at which the 740 operated was causing the bolt heads to over-rotate when the bolt was at its rear most posistion. This was causing the locking lugs to hammer that rail to the point that dents were raised enough to cause the bolt to stick momentarily in the rear posistion. In bad cases, the bolt handle had to be forced forward to get the lugs unstuck. In the field, most shooters simply attributed this phenomenon to a "dirty" gun and would clean and oil it. The problem of course would not be resolved, and thus many shooters began to curse the gun that had been serving hunters so well for several years. In worse-case scenarios, the bolt would become locked solidly in the battered dents and would have to be disassembled to get the bolt out of the rearward posistion. To resolve the problem, Remington had to create another model.

The last year of production for the 740 was 1959. In just under 5 years of its production, with its 5 different grades of configuration, a quarter million 740s had been produced. But the "Woodsmaster's" saga had not ended.

The following year, in 1960, Remington offered the model 742. It also was offered in 5 grade variations, two of which were carbine versions with 18.5" barrels as opposed to the rifles' 22" barrels. Essentially, the 742 was the 740, except the action tube part's weight was increased in an effort to slow the bolt's movement enough to keep the lugs from battering the rail inside the receiver. Also, the barrel's retainer nut was changed with the 742 so a common wrench could be used to remove the nut and barrel. The earlier 740 model had a spanner nut that required a special wrench. The 742's tolerances were loosened a bit also so it was less sensative than the 740 had been to slight variations in the barrel nut's tightness.

The 742 was offered in the .308 Winchester, .30-06 and .280 Remington chamberings. The .244 Remington chambering was renamed as the 6mm Remington.

Still, the bolt lugs battered the reciver rail, however. The problem wasn't as bad, but it still happened. Generally, a 740/742 can stand about 1000 rounds before the bolt lug battering becomes problematic. A gunsmith can stone-polish the raised dents to allow the bolt to operate properly again. After a few hundred (perhaps 500 or more depending upon chambering), the battering will again cause problems. Gunsmithing can again fix the problem with stoning of the displaced metal. However, that is likely the final repair that can be made to the rail before it will allow the bolt head to over rotate and stress the carrier and link pin. The final repair may only solve the problem for a couple hundred more rounds. Since the rail is an integral part of these receivers, once they can't be repaired, the reciver, and hence the gun, is "dead."

Because of the inherent design flaw in the 740 and 742, Remington no longer will service these guns, and has classified them as "obsolete." This practice is fairly common among gun makers once models have been out of production for a few years, so there was nothing wrong with Remington doing this.

In 1981, the 742's long production run was ended. They had made a few small changes over the years, including changing the weights of the action tube as a counter weight, and changing the extractor a bit, but the model remained esentially the same. In total, Remington had produced just under 2,340,000 model 742s. Obviously, a lot of hunters still appreciated a decent sporting semi-auto rifle for hunting.

In 1981, Remington introduced a new variation, the Model Four (not 4, but Four). The Four was a 742 that had a clean look to it, and had a slight redesign to again attempt to end the problematic bolt lug battering issue. The Four was only made until 1988. Not as many of these were sold, but Remington doesn't have any hard figures available as to just how many were made. It was offered in .243 Winchester, 6mm Remington, .270 Winchester, .280 Remington, .308 Winchester (discontinued by 1984) and .30-06. The Four was actually a version of the 7400 variant, to be discussed later.

In 1984, Remington introduced the model 74 "Sportsman." It was only offered in .30-06, and was a base model of the Four. It was only made through 1987, and again, Remington has no hard figures as to the total production of this model available. The 74 was a more affordable option that Remington was using no doubt to compete for a shrinking hunting market against more competition that also were offering affordable guns and semi-autos.

Also introduced in 1981, and still in production today, was the model 7400. The 7400 never has had an official moniker, and really has not earned one. The 7400 is the best design of all of the 740 series. However, with a shrinking hunting market, and with more and more competition, the 7400 just never has become the legend that had its predecessors. The 7400 has essentially been a hunting tool where the 740 and 742 were considered more special.

The 7400 has been offered in 6mm Remington (discontinued in 1995), .243 Winchester, .270 Winchester, .280 Remington (7mm Express), .30-06, .308 Winchester, and .35 Whelen. The .280 Remington was labeled the 7mm Remington Express from 1981 until it was renamed the .280 Remington in 1988. The .35 Whelen has been the largest bore and most powerful chambering of the series. This chambering was only offered between 1993 and 1995 however due to lack of interest.

There have been 4 grades of the 7400 model, not including the Four and 74 previously discussed. A carbine version, with the 18.5" barrel like its predecessors had, as well as 3 rifles with 22" barrels. Some grades have had decent wood with a standard checkering pattern. Others have had oil-stained wood with fancier checkering. And still others have possessed synthetic stocks and matte blued finish. As with all of the earlier models, the 7400 comes equipped with adjustable Remington iron sights, and are drilled and tapped for scope mounts.

The biggest changes made to make the 7400 were designed once again around an effort to resolve the bolt lug battering problem. The action arms were beefed up to both strengthen them and to increase weight. The bolt carrier was permanently fixed to the action arms to strengthen the connection. The inertial weight was made lighter, but longer in an effort to spread the operation over a longer period of time instead of a sharper snap that the 740 and 742 created. The cone in the front of the weight (action tube) was increased to allow the gas pulse to expand more and thus slow the operation of the weight a little. A "flex arm" part was added to help secure the action arms which allows the parts to flex a very small amount and thus slow the operation yet some more. All of these changes have managed to slow the cyclic rate enough to virtually end the bolt lug battering problem that plagued the 740/742, but the problem does still exist. On 7400s I have inspected, all that have seen more than a few rounds have shown shiny spots on the rail where the lug contacts the rail. However, Remington removed the 15 small lugs in favor 3 larger lugs. This change increased weight on the bolt a little which once again works to slow the cyclic rate, but also serves to make the contact with the rail one wider impact instead of 5 smaller impacts. The wider striking surface spreads that impact over a wider area, and serves to keep the rail from experiencing the amount of metal displacement that the earlier models showed. I have never seen a 7400 that had enough lug battering to create a problem. This is partly because hunting rifles do not normally experience the number of shots that it would require to cause this problem anyway, but mainly is a result of Big Green finally making enough changes to have slowed the process enough that the vast majority of 7400s will never see the number of shots it would require to damage the rail. In short, Remington fixed the problem for all intents and purposes.

The other big change was the switch from using a barrel extension in which to lock the bolt head, to actually having the lug seats milled directly into the breech of the barrel. This allows the gun to handle higher pressures better. It also served to remove an extra piece.

There are many 740s and 742s still is service, and they should remain in service. The shooter should simply be aware that someday, the bolt will hang briefly upon the rail. After that begins happening, the issue will not be resolved with cleaning and oil, but will require a gunsmith's services. The shooter also should keep in mind that the problem will occur again in a few hundred shots, and eventually the gun itself will be relegated to a "wall-hanger" or a "parts gun" status. Also, when looking at a used 740/742 at a gun show or yard sale, the shooter should keep in mind that the gun will eventually die, and unless the seller can offer advice as to how many shots have been fired, or if any repairs have ever been done, the buyer should beware that the gun could be on the market because the problem is advanced. If the problem is well developed, sharply racking the bolt back and then releasing as fast and hard as possible can sometimes reveal the slight hang-up of bolt lug battering, but more often than not cannot reveal it if the problem is not advanced. Keep in mind that the magazine must be removed or the bolt will lock open.

All of these guns require a standard amount of care. The receiver, being closed, isn't prone to collecting water or debris in the field. To clean the gun, the action can be opened and locked back with the magazine installed. Simply clean the bore as normal, except it must be done from the muzzle unless a "snake" is used. The chamber especially must be kept cleaned and dried of excess solvent or oil. The speed of the cycling begins opening the bolt and thus extracting the casing while the brass is still expanded and gripping the walls of the chamber. Any solvent, oil, or debris in the chamber, or on the casing upon chambering and firing can cause the brass to sieze. The extractor on the bolt head is small, and can rip part of the rim off the case head, leaving the spent casing siezed in the chamber until the bolt attempts to feed the next cartridge into the rear of the spent casing. This of course will cause a serious jam.

To clean the open action, simply use a swab with solvent to wipe the bolt head and any accessible parts clean. A bent toothbrush also can be used to scrub parts. Dry the excess solvent from the parts that are accessible, and then apply a drop of oil on the operating rails. That is all that needs to be done for general maintenance.

The forearm can be removed to access the gas system. These parts should only be disassembled by a gunsmith, but the shooter can clean them as best as possible as above, and lightly lube the bearing parts' contact points.

Any feeding problems that these models experience are generally the fault of the magazine feed lips which can be bent. Magazines are still offered for these guns, so a spare should be obtained while they are available. A lost magazine turns these guns into unique single shots.

Accuracy of all of these models is about equal. None can become true target or varmint-class rifles. This is because the semi-auto action cannot lock each round secure each time the same way, and because the barrel is burdened by the gass system with its harsh and very violent operation shot after shot. However, as a big game hunting gun, it is more than adequate for most shooters' needs. Groups often can be kept to 1 m.o.a. but 1.5 m.o.a. is more usual. Again, however, this is all the accuracy that most hunters require. As a fast-handling brush or timber gun, the 740 series guns, and especially their carbine versions, shine. These guns offer plenty of short to mid range power with rapid follow-up shots. With the safety posistion above and behind the trigger as with the other similar Remington trigger groups (870, 1100, 760, etc.), the gun can be put into very quick action. While the cartridges offered do have decent long range power for medium sized big game, the accuracy may not be sufficient to allow ethical shots. This decision however can only be made by each individual shooter with regards to their own skills and the loads they have chambered.

The 7400 shows no signs of being discontinued anytime soon. It is a strange mixture of an old design that probably should have died off long ago except that it has had a reputaion as a classic hunting arm for so long, and newer designs that deserve to remain in service for some time to come.

There are many shooters that now disparage the 7400 out of memories of problems they or others had with its predescessors, or because they have personal prejudices against semi-automatic hunting rifles or the guns' appearance. However, all of the guns are unique and deserve respect as hunting rifles. With proper care, they operate very well, and with sufficient accuracy to satisfy just about any hunter. I must admit to being one that once disliked the 740 series based upon their looks, but after learning about their design features and even their problems, I have gained respect for them. The 7400 variants are the best of all the variants, but for me, it is the classy looks of the 742 Woodsmaster series that I most admire, problems and all. As long as one knows the quirks in the gun, a fond appreciation can develop with any of the models. With appreciation, even a gun with some quirks can earn itself a fond reputation from its user in the woods.

stsimons, don't let the naysayers discourage you from having a good time with your 742. Few can say that they have a nearly new 31year old rifle in probably the best cartridge ever made. Many of the problems associated with it are a direct result of the lack of proper owner maintenance.
Maintain a cleaning and lubricating regimen, and it will last at least your lifetime.

I have one from the early 1960s in 30:06. After a new magazine and a good cleaning it shoots every time.

Shoot yours and make sure it functions well and then do what you want to mod it and just enjoy it.

I own a 7400 in .30-06. It's my favorite rifle. Probably becasue I bought mine new in 1986 when I turned 18. It was my first rifle. I tought myself to shoot becasue I didn't know anyone who shot. I put a Redfield Low Profile 2X7 scope on it and have shot probably over 2,000 rounds through it as it was my sole rifle for a long time.

I wanted to get into hunting then but didn't know anyone who huntned nor did I know how to get into the sport. So, I continued to shoot...and shoot...and shoot. I did keep mine pretty clean but only wet patches down the barrel after each range session. I have never had 1 jam (except for shooting managed recoil ammo from Remington). But, those are really light loads and wouldn't cycle the action. I had to manually cycle the action after each shot.

That rifle is 100% on 1 shot kills on the few hunts that I have gone on. Accuracy at the range is a best of 1.5" at 100 yards and an average of 1.8" at 100. And, that could very well be me...even if I wish it weren't. The best factory ammo for my rifle is the Remington Cor-Lokt in 150 grain with a close second being the Winchester silver tip in 150 grain. Worst is the Federal Fusion in 150 grain. But, that still is only just over 2". Still decent enough for hunting purposes.

Now that I just bought a Winchester M70 in .308, that 7400 might not see as much action, if any. But, it's still my favorite rifle and my 3 boys will learn to shoot it some day. I got a lot of use out of it and it never let me down. Trust me...with all the negative publicity about those rifles over the years...I tried to hate it. But, I just couldn't get myself to do so.

I have owned about 8 or 10 of them. The smaller calibers, 243, etc are more accurate. I have had several 30-06's. Notoriously inaccurate.
My first I tried about 8 different bullets, 5 different powders and so forth. It would not reliably hit a 5 gallon bucket at 100 yards. With a 3-9 Redfield. Only 30-06 I ever bought to use myself. Traded for several just for trading purposes.
I only saw one 30-06 that would shoot at all; my Dad had a 30-06 carbine that would shoot 3" groups, best I ever saw out of one. I shot an awful lot of them, siting them in for friends. My friends called them 'slush boxes'.
I owned 3 243's and my Dad had a 6mm Rem. These would shoot 1' to 1.5".
The 30-06 are prone to what my gunsmith calls 'chamber cancer'. A little rust in the chamber and it only shoots once. Chamber gets minor pitting and extractor pulls the rim off the cases. My smith says it only happens to 30-06's.
Never seen one work again afterwards. New barrel would fix them; nothing else worked.
Wife has a 740 she inherited from her Dad; chamber cancer.
Make sure the chamber is kept oily when not in use.

My Dad got one that nearly 40 years old. It get 3 rounds fired to check the scope and
Dad gets a Buck a year with it usually 1 shot and at 300 yards or less. His is a 30-06

Just treat them nice and they will last a lifetime.

i got the same gun essentially for free a few months ago. It had been shot to the point that the locking lugs chewed NEW locking grooves in the bolt rail... it would freeze back hopelessly every time fired, and you had to beat the bolt handle with a mallet to get it to unlock.

I dremeled out the are where the lugs were touching the receiver, and the freezing problem stopped. It still jams once every 5 or 6 rounds, a failure to go into full battery. The problem NOW is that the bolt is bumping into the rear of the magazine, and slowing down enough that it doesn't make it into full battery, but can be gently pushed the last inch into the chamber.

The thing has been nothing but problems from day 1.

LOL! You get what you pay for.

I have had a 740 in the past and have a 750, currently. Both in 30.06 and both very accurate for a semi. The 750 had some magazine related feed issues initially and has been flawless since.

I've had a few. Cleaning them well and keeping them lubed will keep them running. Use a good gun grease on the frame rails and inside of the reciever. I have not heard of problems of accuracy or rust with the 30-06 but if you use surplus ammo which is corrosive or hot loads or don't keep it cleaned and lubed, you will have problems. I agree that they are not a range gun. They can't take the use of a military rifle but are lighter and in general more accurate except for U.S. rifles.
That was a very good article on the 740 series. Thanks for posting it.

My dad had a .243 version for about 15 years, which jammed all to hell one day due to the locking lugs on the chamber fusing to the bolt. Apparently some from the mid-80s had heat-treat issues.

Before that incident, though, it was reliable, accurate, and simply fun to shoot. :) I'm not sure how much it was shot, but knowing my dad, he probably didn't clean it. Ever. :o

theres a ton of them in the woods up here. Its probably the most popular deer rifle in the midwest. I delt with many of them and personaly wouldnt have one if it were given to me but thats me. I agee with 351 winchester. there a decent gun for the guy that buys a box of shells and still has some in the box 3 years later but shoot them and they will fail.. If it were me id swap it for something else while its still like new.

I have a 742 Carbine that I bought in 1988 for $135.00, half a case of beer and two dressed racoons. In the 22 years I have hunted with this rifle, I have not had a single malfunction. I have harvested somewhere in the neighborhood of 75 whitetail deer with the rifle. I live in Louisiana where the legal limit is 6 deer per year. Probably 100 coyotes have departed the thickets at the muzzle of this gun. I cleaned the rifle once a year just prior to each hunting season using penetrating oil, wire brush, boiling water and Norton Honing Oil. I have fired somewhere around 300 rounds through this rifle. No telling how many was fired by the previous owner. The 742 action has been reliable for me.

I had one that I used to take several deer. It was used and abused when I got it.

You probably have a good rifle there. Just clean and lube every time, and have fun with it! My 742 was an accurate rifle. You should be fine shooting the 180 grainers through it. Just maintain it, and have fun!

Congrats on the new rifle! :)

I have a 740 in 30-06 that I inherited from my grandfather. The rifle was manufactured in 1956. When he passes away the rifle sat in a soft case in my grandmothers attic for about 25 years. She passed away last year and that's when I got the rifle. As soon as I got it I cleaned and lubricated it and set it in the gun cabinet. I was out today to sight my rifles in for the upcoming hunting season. I also have a savage model 111 bolt action with a synthetic stock in 30-06 and it took an entire box of rounds to sight in the savage. I picked up the remington and keep in mind that it hasn't been sighted in since the late 70's and my first 3 rounds were in a nice 2" group at 100 yards using remington core-lokt 165 grain springfield rounds. My grandfather took several whitetail with that remington and I plan on taking several more with it. The savage is going to spend this season as a backup gun.

jji, same with my FIL. He had a 742 in 30-06 and killed a lot of deer with it. I shot it a few times and it was a reliable 2 inch shooter, fine for deer hunting. He said that it had never jammed. These may be a little like a box of chocalate, perhaps more magazine damage or poor cleaning than anything else. I would just advise a man to shoot it and see for himself.

I am glad you “updated” this thread or I would not have seen Saturon’s interesting essay.

The speed at which the 740 operated was causing the bolt heads to over-rotate when the bolt was at its rear most position. This was causing the locking lugs to hammer that rail to the point that dents were raised enough to cause the bolt to stick momentarily in the rear position. In bad cases, the bolt handle had to be forced forward to get the lugs unstuck. In the field, most shooters simply attributed this phenomenon to a "dirty" gun and would clean and oil it. The problem of course would not be resolved, and thus many shooters began to curse the gun that had been serving hunters so well for several years. In worse-case scenarios, the bolt would become locked solidly in the battered dents and would have to be disassembled to get the bolt out of the rearward position. To resolve the problem, Remington had to create another model.

This section and the rest of the text inform me that using heavy bullets and slow powders is very bad in these rifles. My experience in Garands, M1a’s and my PTR91 has taught me that heavy bullets shift the pressure curve, change port pressure (no gas port in the PTR) with the effect that more gas gets into the gas system, accelerating the recoil of the bolt. Unless of course the powder charge for the heavier bullet is reduced to the level that using a heavier bullet is pointless.


I would advise anyone using these rifles to not go heavier than 150’s, keep velocites around WW2 levels (2700 fps) and to use powders no faster than IMR 4895. I have shot a couple of pounds of IMR 3031 in the M1a, our Club President uses it all the time in 30-06, so it should work just fine and as it is faster, the pressure drop at the gas port should be quicker.

Wisner’s has a very interesting section on this series of rifles.

I got a used 742 in 30-06 about 35 years ago. I shoot left handed and didn't like bolt guns. I put a Leupold scope on it. That same gun and scope is what I still hunt with today. I would not even try to guess how many 150 grain Remington core-lokts went down that tube, or how many deer I have killed with it. It like me is showing its age. The blueing is worn off from many hunts, but the gun is sound and the wood is still good. It has never failed me. On a side note it is the loudest gun in the woods. Shoot your new gift and enjoy it. Hold it tight to your shoulder and wear ear plugs.
