Title says it all. Being a 308 is 7.62x51mm and Mosin nagant is 7.62x54mm you would think they would. But has anyone tried? I ask because theres alot of really nice 308 hunting ammo
 
No
Absolutely not.
Don't even think about it.

And, no, they are not both .308.
 
The bullet diameters are different for 7.62x51 and 7.62x54R. .308 and .311, respectively.(IIRC) 7.62x54R is rimmed, 7.62x51 is rimless. Not to mention the different pressure levels, etc.
 
If you're going to do something that stupid

...could you at least set up a videocamera? That way, your death/maiming can be used to help others.:what:
 
An example of how the metric system isn't any more clear than traditional measurements. Just looking at the numbers, it seems perfectly reasonable. But once you look at the CARTRIDGES, you realize at once that they have absolutely nothing in common. The 7.62x54R is closer to the .30-30 or .30-40 Krag than the .308.
 
If you are going to try the .308 in there, why not try a 30-06 in the rifle- after all both the 7.62 and 30-06 were used in WWII. Just use a large lead hammer to pount the bolt shut, come to think of it, a 8x57 cartridge might chamber even easier than a 30-06:uhoh: :eek: ;)

Use the ammo that was intended for the rifle- your fingers, eyes and skull will thank you for it.
 
sevenpoint62mm

The best investment you can make is a reloading manual...any of the big names will do, Lyman, Speer, Hornady, etc.

Even if you don't reload, buy yhe manual and read about the cartridges. These manuals give you great information about cartridges, dimensions, pressures and the like.

They even give warnings against doing silly things like trying to fire cartridges in weapons that weren't designed for that cartridge. ;)
 
I found that I could form C4 into the correct shape of a 7.62x54R cartridge. Can I fire this in my Mosin?

54. C-4 can make a dull day fun.:D
 
Um guys? Did you always know this much?

I didn't always know the answer to this and it would've sounded like a reasonable question once.

Be nice fella's just say no in a polite way ;)

7.62 I'd say it would be ill advised.
 
You're right. Sorry, I don't mean to be nasty. sevenpoint62mm is smart to ask the question before trying it out !

I almost had a bad experience when I got my hands on a Steyr M95. Thankfully did some research and discovered that the rifle fires 8X56 mm which is different from the normal 8X57mm !

Only use the exact ammunition that a firearm is designed for. Anything else could be catastrophic.
 
For those who say 7.62x54R is weak, here is some data from S&B, comparing three.

Bullet cal./weight.......................muzzle velocity.................muzzle energy

7.62x54R/174 gr HP................... 2615................................2647

.308/ 168gr HP............................2628................................2579

30-06 Spr/ 168gr HP...................2786................................2897

Not too far apart, are they? I selected bullet weights close to each other, your results may vary....:cool:
 
Yes, the question was NOT unreasonable. It's perfectly fine to fire .38 Special in a .357 Mag chamber, and the .357 Mag is a slightly longer version of the .38 special. So looking at the metric numbers, it seems as though 7.62x54 is a slightly longer version of a 7.62x51.

And indeed you won't always find .38 Special or .44 Special marked on the side of their magnum big brothers, but it's still fine to fire them.
 
It is quite illuminating to go to http://www.darwinawards.com/ and type 'gun' into the search function there.


I like this one:
(1990’s, United States) I heard the following at work in the gun shop. The events described below (if it’s not a legend) occurred in the 1990’s in the southwest.
A small-time hood (about to be even smaller) broke into the home of a World War Two veteran and stole, among other things, the old G.I.'s .45 automatic pistol, which he used in battle in the 1940's. The hoodlum then reported directly to a local convenience store and proceeded to rob the cashier while brandishing his new pistol. The cashier, no dummy, followed orders and handed over the contents of the register.

Our thug took the money and turned to leave, but suddenly decided he didn’t want to leave a witnesses… other than the security camera, that is. He leveled the pistol at the cashier and pulled the trigger.

"CLICK!" went the gun.

At this unexpected development, the puzzled crook looked straight down the barrel of his weapon and uttered the words, "What the...?"

As it turned out, the WWII veteran had WWII vintage ammunition in his WWII vintage pistol. Priming caps over time are known to lose their "spontaneous" nature, particularly if stored improperly, causing what is known as a hang-fire: The primer smolders into a delayed ignition.

Such was the case here.

Just as the puzzled crook had the barrel pointed squarely at his own eye, the hang-fired primer detonated, sending a half-inch chunk of lead and associated hot combustion gases directly into the felon's skull at 900 feet per second.

The range was less than six inches.
The body could only be identified by fingerprints.

As the story was related to me, the police officer who responded to the original gun burglary was also at the scene of the armed robbery. He picked up the .45 and verified the serial number, then returned it to the WWII veteran.

Case closed.
 
There was a group of Mosin Nagant rifles rechambered for the 30/06. Most considered the conversion unsafe.

Ballistically it would be very hard to tell any difference between the 3 cartridges. On either end.

I understand that US soldiers who used the Mosin Nagant actually came to prefer it to the Springfield.

Myself, if I had to shoot the Russian cartridge, would prefer an 1895 Winchester.:D
 
It was a simple logical question considering they're both the same diameter with yes or no as valid answers. Hell you wouldn't think a 38 cartridge would fire in a 357 looking at the calibers alone. No need to talk down to peeps., sh1t.

I was asking because I gave my my nagant to ny father-in-law for hutning and he can't find hunting rounds in his BFE (far south LA) so I thought 308s might work since they are so common. Oh well so much for that.
 
However, 7.62x54R and 7.62x53R are the same and will fire in a Mosin Nagant.

Don't get down about it sevenpoint62mm. You were right to ask the question. If he doesn't mind ordering ammo mail order, www.natchezss.com has some Sellier & Bellot soft point or perhaps somebody here can suggest something better.

Funny story Steel! Guns can't cause crime all by themselves, but apparently they can stop it all by themselves. Gotta love the good 'ol 1911A1. It's Judge, Jury and Executioner all rolled up in a solid steel, single stack frame.
 
7.62mm - It was a worthy question. There many confusing things about caliber nomenclature that is not always easy for a newbie, and even some old timers, to decipher. Before I got into guns and shooting I thought a .308 was a bigger diameter round than .30-30, .30-06 etc becuase of that extra .008 on the caliber designation. I also thought the .303 was smaller than the .308 (.303 actually fires a .3105-.312" bullet). Same idea with the various .22 centerfires (.220 Swift, .223 Rem, 22-250, 218 Bee all fire .224" bullets)
 
The bullets would be close enough but the cartridges are not. The 7.62x54 has a tapered rimmed case. The 7.62x51 does not. Very different cartridges. There is tons of 7.62 x 54 ammo both FMJ and softpoint that sells for a lot less than .308. Check out your next area gunshow.
 
GI .45's are sweet

Just as the puzzled crook had the barrel pointed squarely at his own eye, the hang-fired primer detonated, sending a half-inch chunk of lead and associated hot combustion gases directly into the felon's skull at 900 feet per second.

why doesn't this happen to more crooks ;)
 
.308 war story

Short and sweet answer NO.

but to elaborate.


I have heard an old war story that this was done in S.E. Asia and personaly I give little credence as to it working, but if it did fire and not ruputure the case the shooter would need a long stick to push the case out of the chamber as the rimless case would not touch the extractor in most cases.

As others have said, please do NOT try this .
