Back some years ago when the infamous Miami shoot out occured which resulted in a 9mm round that failed to penetrate to the heart because it had to pass through an arm and the main trunk of the body a great hue and cry went up for a better police type cartridge. Although the Gov't understood little of ballistics and still has not learned much the question remained , "Was there a better cartridge than the 9mm for police work.

Although the failure of the 9mm that day was in no way due to the caliber. The 9mm has more than enough penetration to have worked that day if a differently designed bullet would have been used the Government could never have been convinced of that fact. The bullet did exactly what it was designed to do. It expanded and did not over penetrate. Of course the Government like everyone else wanted the magic caliber that would never fail. It wanted a caliber that would never overpenetrate or never fail to expand and never fail to under penetrate. Of course no such round ever existed or will exist but one wonders if 1. There could be a better caliber and 2. If in fact the Government went the wrong way in the choosing a new caliber. In other words they went bigger in caliber rather than of all heresy smaller.

It has been well known amoung a few experts that as caliber gets smaller and velocity gets higher a tremendous increase in penetration occurs. Years ago P.O. Ackley after astounding the world in his Arisaka experiments in which he failed to deliberately blow them up stood the world on its ear yet another time by proving that very small high velocity projectiles like the .220 Swift penetrated armor plating while the traditional 30-06 armor piercing round actually failed to penetrate an armored half-track.

He was even laughed at but further astounded everyone when actually shooting 600 pound ferule burros with the .220 Swift which outperformed bigger calibers and killed like lightning compared to the heavier caliber weapons that were also used that day.

All this was not lost to some military arms developers which years later resulted in FN's new .22 caliber assault pistol that out penetrates any handgun caliber made and it does it without expensive and hard to make armor piercing bullets. All this was necessary because of the new bullet resistant materiels being used in military clothing and helmets.
.

Although civilians will never be alowed to use such weapons because of their penetration (at least not here in the U.S.) this all brings us to the queastion "What new caliber based on this theory would be a superior police and civilian round?

It was also proven even before Ackley's time that calibers that were small but of high velocity like the .30 Luger or even faster bullets fired out of the 30 Mauser could drop a 1,300 pould steer in less than 30 seconds and without the use of expanding bullets.

While thinking about the old .30 Mauser it is just too long to work through the actions of most existing auto loading pistols. But something like a wildcat caliber such as the 30/357 Sig. would work through such actions.

The advantages would be:

1. Superior penetration to what is currently being used.

2. Low recoil which gives faster recovery time between shots and factoring in the human element will enable the person to shoot it more accurately on a consistant basis.

3. Less wear and tear on the pistol itself giving much longer service life.

3. Excellent inherent accuracy becuase of its smaller caliber and lower recoil. Factory records show that standards for accuracy when building weapons decrease as caliber and velocity increases. Remington 40x factory records prove this.

4. High velocity and very flat trajectory making it easier to hit at unkown and much longer ranges.

5. When using expanding bullets, a caliber, because of its high velocity makes it easier to design bullets that will expand more violently and much more reliably than bigger heavier slower moving bullets.

6. A caliber because of its small diameter and high velocity will retain its high velocity better as the range increases than the bigger calibers which tend to slow down quicker because of their inferior ballistic coefficients.


Although all this goes completely against what has been taught over the years and the people who have been beating the big bore drums for years will never accept such different thinking the fact remains that people like P.O. Ackley never accepted any information on firearms that he could not prove or duplucate himself.

It was well known in Europe that small high velocity calibers like the .30 mauser with expanding bullets killed deer at pistol ranges very well indeed and the same thing was proven on this side of the Atlantic many years ago when people used .30 Luger carbines and even stadard barrel length .30 Mauser pistols with shoulder stocks attached.

Maybe its about time for someone to build such a new pistol cartridge like the 30/357 Sig.and give it a try with various weight and various brands of modern bullets that are now available because for years we may just have been throwing out the baby with the used bath water without even realizing it.
 
"ferule burros..."

He shot flat wooden donkeys?

Congratulations.

You've just reinvented the 7.62 Tokarev.

It should be as underwhelming as the original.

"6. A caliber because of its small diameter and high velocity will retain its high velocity better as the range increases than the bigger calibers which tend to slow down quicker because of their inferior ballistic coefficients."

Also, I really hate to break this to you, but the inferior ballistic coefficient of which you speak?

Let's see...

A .30 cal. bullet for such a cartridge would likely be along the lines of Hornady's 110-gr. lead round nose, the kind used in the .30 Carbine or .30 Herret.

It has a ballistic coefficient of .150.

The ballistic coefficient of Hornady's 125-gr. .357 Mag. Hollow Point XTP bullet? .151. That's right. Flat point.

.40 S&W? 180 gr. HP/XTP bullet? BC of .164.

45 ACP? 200 gr. HP/XTP? BC of .151.

Rule of ballistic thumb for you.

If two bullets of the same ballstic coefficient start, one heavy and fairly slow, and one high velocity and light, the lighter, smaller bullet will shed velocity MUCH faster than the heavier, larger diameter bullet.
 
Personally, I think necking the 10mm case would be better - keep the OAL closer to the 1.23" range, for proper feeding in a 1911. A little more capacity to boot, for more velocity.

That said...don't expect me to invest in any chambering reamers. Not much point to it, unless you're one of those types who wants to make super-small reloadable cartridges.

If I ever stumble across a .30 Luger 1911 barrel, I'd probably buy it for the hell of it, but make a project out of it? No.

One old hunting bud used to swear by his .22-250 for Texas deer...until you got a few beers in him. Then he'd start admitting to losing a few wounded animals. He finally switched to a .25-06 two years ago.:)
 
600 pound ferule burros


:confused:

Did you mean "feral"?



Hmmm. Did I miss something? Or did we leave out the factor of sectional density?


At any rate, the underlying idea is correct - velocity penetrates. Ever seen a straw blown through a fence board by a tornado? Lousy ballistic coefficient, I'd bet.

Of coursse, you've got to deliver the velocity to the target. That's where ballistic coefficients come in to the equation.
 
1. Superior penetration to what is currently being used.

...

5. When using expanding bullets, a caliber, because of its high velocity makes it easier to design bullets that will expand more violently and much more reliably than bigger heavier slower moving bullets.

"Violent expansion" and "superior penetration"? Sign me up!

Quick! Get on the phone with Marshall, Sanow, and Fackler, before someone steals your idea; you could be the next Burczynski!
 
You've just reinvented the 7.62 Tokarev

You were not paying attention to what I was posting.

The Tokerov will not fit into many of the popular 9mm size pistols. The 30/357 Sig. would.

It would also be a plus if the producers of the new Cartridge would increase the velocity over that of the Tokerov even if only slightly. The point being that anything that is new is considered better by many people (not that it really is). But many people would not want a gun in the old, old Tokerov chambering but would be more than willing to try something that they perceived to be as new and differnet.

Case in point. Many of the new short magnums do absolutely nothing ballistically that the older cartridges have been doing for years but because they are new it increases gun sales. People think that a new design is better even though many times it is not. The Old, Old , 22-250 or the .220 Swift is more than capbable of shooting 5 shots into 1/2 inch and even slightly smaller groups at 100 yards, so is the new 22 WSM (short fat magnum) going to be any better. No it is not because when fired out of rifle actions that were originally designed for light sporter barrels they do not have the necessary stiffness to support big heavy weight varmint type barrels like the custom super heavy bench rest single shot actions do. But the public does not know this and believes the advertisments that the newer cartridge is superior and so they buy it and are happy with it.

The same princlple applies to the 30/357 Sig. Would it be any better than the .30 Mauser or .30 Tokerov. Well probably not unless the designers could get more velocity out of it and even then the advantage would be slight. But the point is people would buy it, try it , probably like it and when enough real life data was compiled in shootouts people would begin to see that it was indeed a deadly cartridge. Something that Winston Churchill could have told you over half a century ago or any of the Communist Chinese soldiers that used it to wipe out the Nationalist Chinese soliders in their civil war. No one told them the cartridge was supposed to be inferior and since they had confidence in it it worked for them because it proved not be inferior. Dead soldiers piled high proved it.

I like the super flat shooting .30 Mauser and I hit much targets way easier at 100 yards than the slower moving bigger calibers. The supersonic crack lets you know that the bullet is really screaming for a pistol cartridge. Getting up into the 1,600 fps range in the bigger calibers results in a behemouth of weapon that is impractical to carry and impractical to shoot much because of the recoil. Using a lighter made weapon in the bigger calibers that have that much velocity results in very short service life.

The point being that since few people use the high velocity .30 caliber pistol cartridges few are aware of its advantages. I for one would buy one just to see if it could beat out the old .30 Mauser by much , it probably would not beat it by much but it would be fun trying.
 
A 30/357Sig would have to start with either a 10mm or 10mm mag case.

The 357Sig case already has too short of a case neck, and the 40Short&Weak is even shorter, if you neck it down.

I've read that minimum case neck length is at least one caliber size. Preferably 1.5 times.

I would build it from a 45ACP, at least the prototype, just to get more case support.

So, when are you going to have it made? When are you going to have some terminal ballistics data?
When are you going to have reliability data?

:D
 
"Getting up into the 1,600 fps range in the bigger calibers results in a behemouth of weapon that is impractical to carry and impractical to shoot much because of the recoil."

Funny, 1,700 fps. true, and more, out of my 4" Model 28 is easily doable, and the recoil isn't harsh, either. For any one who's interested, that 800 ft. pounds of energy.

Same velocity out of my 4" Model 19. Certainly quite a bit snappier recoil, but still not bad at all. Not unlike a light-weight 40 S&W.

Neither handgun is a stretch to carry, either.
 
Oh, by the way, I was paying attention.

Here's your statement...

"While thinking about the old .30 Mauser it is just too long to work through the actions of most existing auto loading pistols."

Kind of a nebulous statement, don't you think?

MOST existing auto loading pistols?

You mean the 1911s, the Berettas, the Taurui, the S&Ws, the Rugers, the Glocks, etc. etc. etc.

All of the full-size models perfectly capable of handling the Tokarev round.

Even some of the smaller compact models should be more than capable of handling the Tokarev round. For example, the Glock compact in 10mm.

"But the public does not know this and believes the advertisments that the newer cartridge is superior and so they buy it and are happy with it."

I'm confused, with that statement you're talking about the .30-.357 Sig, right?

I will, however, agree with your broader assessment of the new series of short magnums. I'm not convinced of their utility or overall practicality of these cartridges.

Severely overbore springs immediately to mind.

I'm also very interested in seeing what sort of barrel life will be realized out of these rounds. I'm suspecting that it's not going to be very good at all.
 
1. Superior penetration to what is currently being used.
If you want more penetration now, just pick a poorly designed JHP (eg, one that clogs up with cloth) or a FMJ.

5. When using expanding bullets, a caliber, because of its high velocity makes it easier to design bullets that will expand more violently and much more reliably than bigger heavier slower moving bullets.

If this were true, one wouldn't expect to see big, fat, slow .45ACP JHP's that expand reliably. But we do. For example, from the FBI gel studies, the Remington Golden Saber expands about 55% (to ~ 0.7") in both bared and clothed gelatin, and it's only going 871fps. There are many more .45ACP JHP's that exhibit this behavior. See http://apollo.demigod.org/~zak/firearms/fbi-pistol.php?sort=grade1

A bullet desiged to run at 1300-1500 fps is going to have to resist expansion so that it won't over-expand and have limited penetration.

If you fire bullet designed to expand at about 1000fps at 1400-1600fps, it's going to "splat" and fragment instead of penetrating. This is what would happen if you use a varmint bullet on large game - similar to what people reported when they used the wrong Ballistic Tip bullets on deer a while back.

So if you have a bullet designed to expand properly to achieve the desired penetration (lots) at 1500fps, if it hits at 1000fps, there's a much smaller chance it will expand.

When we talk about game dropping "like it was hit by lightning", we're usually talking about hitting it with something like the canonical .270 load, which is going over 3000fps/

If you really think some sort of .30-caliber necked down cartridge has merit, it should be easy enough to evaluate: pick a platform you can launch them from (eg. Tok, some pistol with sabots, or a rifle loaded down a bunch), get the bullets you think would suit your scheme, and shoot it into calibrated ballistic gelatin.

It has been well known amoung a few experts that as caliber gets smaller and velocity gets higher a tremendous increase in penetration occurs.

Sorry, but that is incorrect. A 5.56 penetrates less than many 9mm, that is why many SWAT units are using it for CQB/engry guns. Goes through a vest but will not over penetrate on flesh.

All this was not lost to some military arms developers which years later resulted in FN's new .22 caliber assault pistol that out penetrates any handgun caliber

Again, incorrect. The round in question is the 5.7x28mm SS190 and was designed to penetrate body armor but not over penetrate a human. The SS190 has unique design, utilizing two metal inserts. The tip of the ogive has a steel penetrator followed by an aluminum core that is heavier than the forward tip. This causes the bullet to tumble in soft body tissue after 2 inches of penetration. This design virtually eliminates the risk of over penetration. This also creates a large wound cavity and quick incapacitation. The SS190 will perforate 48 layers of Kevlar up to 200 meters when fired from the P90 and achieve the same result up to 50 meters with the Five-seveN handgun.

I think your overall understanding is incorrect and thus your theory has some major flaws in it.
 
the problem I would see is that you would need to develope a new bullet. Current 30 cal pistol bulets anre all in the 10o grain catigory and I think that they are too light something in the 120 to 130 grain class would be better but then you need a longer case neck to support the bullet wich cuts back on powder capasity and you loose velocity.

P.S. ruger made a small run of p89's with an extra 30 luger barrel
+p+ 30 luger anyone ?
 
Right there with ya, George!

P.S. ruger made a small run of p89's with an extra 30 luger barrel
+p+ 30 luger anyone ?

Sure! Czech CZ-52, 7.62x25 Tokarev Czech-specification handloads, Sierra 85gr RNSP, AA #7, 1700+ fps. Piece of cake! ;)
 
Same velocity out of my 4" Model 19. Certainly quite a bit snappier recoil, but still not bad at all. Not unlike a light-weight 40 S&W.

It long been known that the model 19 even with the double heat treatment they recieve is not a gun you want to put a lot of rounds through. This is exactly why Smith developed the heavier model L frame. Gunsmiths of the past have told me it was not unusual to see Model 19's in for repair after firing only about 2,000 full power .357 magnum loads out of them.

I'm also very interested in seeing what sort of barrel life will be realized out of these rounds. I'm suspecting that it's not going to be very good at all.

I think you are confusing rifle barrel life with pistol barrel life. There is a tremedous difference. All one has to do is look at the barrel life of the .30 Tokerof or the .30 Mauser. I have shot .30 Mausers that were at least 80 years old which had untold thousands of rounds shot out of them and they were still giving accuracy that was sometimes better than brand new pistols that I had bought in larger calibers proving not only that the .30 Mauser was not hard on barrels but that it was an outstandingly accurate caliber.

I think the 30/357 Sig would be very similiar to the .30 Mauser ballistically and also have similiar barrel life.

I do not think the public often even gives a thought to barrel life anyway. If they did the market for magnum rifle cartridges would be 1/10 of what it is now. The public seldom thinks ahead as to what the cost actually is when they have to rebarrel a high power rifle and in the case of the new Remington Plastic 712 rifle you can only throw it into the trash because it is not rebarrelable both in mechanical terms and cost terms. So the public just is not going to consider it when purchasing the weapon.

Many of the public never even get around to shooting their weapons enough to wear the barrel out so for them the worry of barrel replacement is not a concern.

I think no matter how you look at it barrel life is not an issue. I think the barrel will last longer than most shooters will.

Again, incorrect. The round in question is the 5.7x28mm SS190 and was designed to penetrate body armor but not over penetrate a human.

I think you are contradicting yourself here. Since the 5.7x28mm does penetrate body armor and the other handgun calibers do not this only proves what I stated in the beginning.

Sorry, but that is incorrect. A 5.56 penetrates less than many 9mm, that is why many SWAT units are using it for CQB/engry guns. Goes through a vest but will not over penetrate on flesh

Here again the U.S. military proved the 5.56 mm with the newer heavier bullets and faster 1-7 twist penetrates old style steel helmets up to 400 meters while the 9mm only penetrates them up to 130 yards and the .45acp only at 30 yards.

I think you were referring to the use of expanding bullets or the use of the older 55 grain fmj military loading that often tumbled when hitting a human target.
 
You either have penetration, or you have expansion. You have to give up a little on one to get the other.

Or you change the bullet, make it one of those Barnes X solids, or Swift A-frames, or Nosler Partitions.

How about just chambering a semi-auto in the 22 Hornet. I bet that would give you penetration as well.
 
BHP9,

You are still not describing the differences in effectiveness in penetrating hard targets, soft targets, and ballistic weave. Why not? They are governed by different mechanisms...
 
I don't understand why you're stopping at an arbitrary .30 caliber. If you use a .17 caliber bullet fired from a necked down .40 case you could get velocities in the mid 2500s. Provide expansion by the same method as a expanding/hinged broadhead.;)



BHP9, the .30 Mauser is not so much an accurate bullet as it is an accurate gun. The accuracy lies in barrel fixed to the sights. Even a .40 broomhandle would display outstanding accuracy. Give credit where it's due.
 
So if you have a bullet designed to expand properly to achieve the desired penetration (lots) at 1500fps, if it hits at 1000fps, there's a much smaller chance it will expand.

You are absolutely correct and this is why people should not place so much faith in expanding bullets. For example you told of the .45acp bullet designed to expand at around 850 fps but as the range increase the expansion will go down or fail to expand at all. Penetration also suffers. Starting out with a caliber with tremendous penetration like the .30 caliber pistol cartridges you have a caliber that penetrate at ranges where other calibers fail because the other cartridges were marginal to begin with. This is not to say that the .30 caliber cartridges will always expand perfectly but at the longer ranges they still will penetrate better even though they too have slowed down in velocity. This was dramatically proven in the Thomson tests when they increased the range while using the slower .45 caliber revolver cartridges as compared to the faster .30 luger cartridge.

In a test with hard cast bullets I once conducted I took an old piece of sheet metal that was about the same thickness as the average 55 gallon steel drum. I shot the piece of sheet metal with hard cast bullets out of a .30 Mauser, 9mm Luger and a .45acp. As the range increased the first failure to penetrate was with the .45 acp the second failure as the range increased was with the 9mm and the last failure was with the .30 Mauser. Proving that the smaller faster pistol calibers do outpenetrate the slower bigger calibers as the range increases. Penetration would have been much better of course with all the calibers if I had used full metal jacketed bullets but the principle remains the same.
 
BHP9, the .30 Mauser is not so much an accurate bullet as it is an accurate gun. The accuracy lies in barrel fixed to the sights. Even a .40 broomhandle would display outstanding accuracy. Give credit where it's due.

I think you misunderstood what I was trying to say. I was giving the Mauser only as an example of how long the barrel lasted proving that the caliber was not hard on barrels.
 
"I think you are confusing rifle barrel life with pistol barrel life."

No, you took a seque over to talking about the new new series of rifle cartridges, and that's what I was talking about.

Overbore rifle cartridges have a very nasty habit of being very hard on the throat and leade, and these "short fat magnums" as you classify them are nothing if not overbore.

As for the Model 19, that's true, it's not known to be the strongest revolver around. What you gain in ergonomics you lose in overall strength.

That does not take away from the fact, though, that the 19 is perfectly capable of handling such loads.

Nor, for that matter, are the L frame or the similarly sized Rugers, none of which are the monsterous behemouths that you apparently think are necessary to fire larger bullets at higher velocities.


"I have shot .30 Mausers that were at least 80 years old which had untold thousands of rounds shot out of them and they were still giving accuracy that was sometimes better than brand new pistols that I had bought in larger calibers proving not only that the .30 Mauser was not hard on barrels but that it was an outstandingly accurate caliber."

Actually, the only thing that it really proves is that that particular Mauser wasn't shot a lot.

If there is one overriding truism about the vast majority of C96 Mausers it is that they come with barrels that are little more than sewer pipes.

Why?

Because corrosive ammunition, hotter powders, and softer steels.

Extensive shooting with European smokeless powders of that time, which were normally double based and high in nitroglycerine and consequently burned very hot as compared to single base powders, or even today's double based powders, led to a lot of washed out barrels, with the corrosive priming taking care of the rest.

Other than that, this is one of the more silly threads I've read this week.
 
It's not officially ridiculous until I suggest that the 10mm be necked down to hold six one millimeter, 30 grain projectiles launched in a sabot traveling nearly 1700 fps. The projectiles would be made of barbed depleted uranium with a hollowpoint filled with 10mgs of concentrated nicotine resin.

Just think of pre-expanded superpenetrators capable of taking out a 602 pound mule sitting in a half-track with a steel pot on his head by heart attack if necessary!
