10mm/10mm mag vs the magnums?

[BigBill]

I read all different answers to the question which one is more powerful? In a revolver.

The 10 mm / 10 mm magnum
Vs.
The 357 mg, 41 mg, 44 mg

Who’s the top dog in a shootout, for accuracy, power?

I read the 10 mm is close to the 357 mag. But the posters say it’s closer to the 41 mg. Is the 10 mm mag closer to the 41 mag? Where does the 44 mag place in this line up.

I understand everyone has a opinion but what’s the honest truth.

Many of the boutique companies such Underwood, Double Tap etc. have 10mm offerings that push hard at the bottom end of the full house loads from Winchester etc. of the 41 mag.

 

[ronbwolf]

Not exactly apples and oranges, but close. If relegated to a revolver, the 10mm, is just another cartridge. .357 if loaded at the original loadings of a 158 gr. bullet at 1500 fps, is quite a handful. Most .357's are loaded much lighter. The 10mm rounds loaded by Underwood, a 200 gr. bullet, at 1200 fps is certainly lethat, and has proven itself against bears. Loading it in a revolver limits it to 6 rounds, and while very accurate, and quick to reload using moon clips, you are limiting yourself for no reason. 10mm is my edc in a 1911. The .41 mag is capable of equaling the .44 magnum, but only with loads that punish on both ends. I love my .41's, but not for edc. The .44 mag is the King, in number of loads, bullet designs, availability, and versatility. Just beware when looking at the "magnums," there is a reason that many of us have picked up lightly used, as in only fired six rounds or less, magnums, on the used market.

Jeff Cooper once stated that the 10MM will do at 75 yards what the 45ACP will do at 35 yards. I had a few 10MM autos and there were only two that would take the stout loads. My delta Elite Locked the slide back at just over 1150 fps. The Desert eagle and the LAR Grizzly wouldn't function reliably at 1200 fps. Never shot any heavy through My Bren Ten. Ruger BH and RH I shot 220 SWC at close to 1550. very accurate. In My Smiths I keep the 220's around 1300. When I ran the Magnum Match at My gun club I required the pistols to belch flame and recoil. Minimum loads 44/240/1250, 41/210/1250, 357/158 1300. When members requested to shoot the 10MM My reply was that They had to get in the right zip code. The 10MM is a great semi auto horsepower cartridge and it is staging a comeback in EDC guns. I sometimes carry the Bren Ten just for giggles when I'm going to be around a bunch of LEO's.

Case capacity is the deciding factor:

Capacity in H²O Wt./gr. (All are Starline cases)

10 Auto = 24.1gr

357 Mag= 26.7gr

10 Mag = 31.8gr

41 Mag = 33.8gr

44 Mag = 37.6gr

.

Powder = power

My experience with the 10mm Auto has been, so far, limited to the Colt Delta Elite. I found the 10mm Auto to be highly versatile, very much like the 357 Magnum. In terms of power, I consider the 10mm Auto to be every bit equal to the 357 Magnum and in original, Norma style loads, it falls between the 357 Magnum and 41 Magnum.


I have no experience with the 10mm Magnum, but it strikes me as being a substitute for a revolver chambered in 41 Magnum. Personally, if I need that sort of power, rather than rechamber a 10mm revolver into a hard to find boutique caliber, I'll buy a 41 Magnum revolver or use the 44 Magnum, which is much easier to find.

 

[shocker]

Powder = power

10 mm has a higher SAAMI pressure allowance than 357.
There's an efficiency gain from gas pushing on a a larger piston.
And 10 mm can use heavier bullets than 357.

So to answer the question, 44>41>10>357 for power potential.

BLUEDOT and shocker are both right. It is both amount of room for powder as well as the allowed pressure in a given case.

I.E. factory 45 colt at standard pressure can't hold a candle to 44 mag at SAAMI pressures. However, if you ignore SAAMI, you can push the same bullet at the same weight out of a 45 colt with less pressure than you can a 44 mag. At the same pressures, the 45 colt is more powerful. However, you must be mindful of whether the gun and cases can handle that pressure.

10mm is NOT more powerful than the 357 Magnum. At its best 10mm is equal to a good 357, everyone that keeps saying otherwise is just repeating BS. 10mm can hold heavier bullets, that's it. As far as the 41 Mag, the old story that the 10mm is its equal is also BS. If you have to compare the weakest 41 ever loaded to the most powerful 10mm ever loaded to try and make your point, you already lost. Too much lore and ego surrounding the 10mm for most people to admit the truth. Underwood makes the hottest factory ammo I've seen in both 357 and 10mm and their 125gr 357 at 1700 fps and 802 ft-lbs beats any of their 10mm loads in any weight. Until someone can provide a 10mm load that bests that, the 357 is still the winner. The 10mm Mag is a different story, but since nobody has ever commercially produced a handgun in it that I've found, it's no more than a wildcat cartridge. Our feelings may vary but numbers don't lie...

Answer is, that within certain limits, it depends. .44M is king of the hill, no matter what, in the lineup you mention. Case capacity and bullet weight rules there. .41M is next, neither 10mm or .357M can quite reach, again, case capacity and bullet weight matters.

Now, when you get to the 10mm vs. .357M debate, is where the lines blur. Powder type, powder weight and bullet weight combinations can make either one superior to the other, but they're all pretty close and whatever you'd happen to shoot probably couldn't tell which one hit them at effective ranges.

I don't shoot a lot of .44M, but .41M is my favorite bus-stopping round, and I shoot it frequently from both a 4" and a 6" barrel. It definitely has an edge over .357M and 10mm. I also shoot a fair amount of .357, from three different revolvers, and 10mm from a 1911. I don't feel that there's significant difference between one or the other (revolver/pistol) in how the rounds perform, aside from barrel length. The 1911 has less felt recoil than the wheel guns, but it's still quite sharp, more than .45 ACP from the same platform.

And rbcd makes a 10mm 77gr at 2400fps for 1015 ft-lbs....

357 Magnum: Smaller bullet, more case capacity.
41 Magnum: Bigger bullet, much more case capacity.
44 Magnum: Much bigger bullet, much, much more case capacity.

10mm Auto is on par with the 357 and is much less powerful than 41 mag or 44 mag.

10mm is much better in an auto than any of the above, and worse in a revolver than any of the above.

The "10 mag" is a boutique round that doesn't really have much following. There's nothing it can do that a 41 or 44 mag can't do better.

To answer your question, the "top dog" is easily the 44 Magnum if you mean tops for power.

Accuracy is going to be a function of the firearm. All of these rounds are capable of exceptional accuracy.

 

[rosewood]

My 10mm holds 16 rounds, 18 with +2, your 357 mag holds 6 rounds. I win!

 

[double-dipper]

Who’s the top dog in a shootout, for accuracy, power?

first one must be able to hit their intended target or threat! If you miss what's it matter? you loose. So it comes down to practice and become intimately familiar with your firearm.

Second I really don't think a BG (bad guy) would know the difference if he was hit by a 10mm, 357 mag, 41 mag or 44 mag

All are very capable of stopping the threat!

44 Mag is still the king but, if you can't hit anything with it its a hammer and a new gun for the BG!

What length barrel are they getting 1700 FPS in? Barrel length matters significantly. I have noticed a lot of load data for 357 mags are using 6" and sometimes up to 10" barrels for their test. Most 10mm test are done in 5" barrels. In my 16.5" 10mm carbine, I am pushing a 180 xtp to 1555 FPS at well over 900 ft*lbs of energy.

Numbers don't lie, but sometimes pertinent details are omitted.

Against 2 legged urban critters all of magnums are more than sufficient. It comes down to bullet construction.
I give the edge to 41mag for accuracy. Underrated cartridge imho.
If you dont reload however sourcing ammo could be a problem and the edge goes to 10mm/40sw

In terms of power, I consider the 10mm Auto to be every bit equal to the 357 Magnum and in original, Norma style loads, it falls between the 357 Magnum and 41 Magnum.

That is true if you go with what Norma printed on the box. That was before YouTube was full of reviewers with chronographs so they were better able to get away with exaggerated velocity claims. I have only found two reviews of people chronographing the original Norma ammo through real guns and in those cases the actual velocities fell 180 and 220 fps short of the legendary numbers printed on the boxes:

Original Norma 170 grain. Claimed 1400 fps, actual 1219.

Original Norma 200 grain. Claimed 1200 fps, actual ~980.

KE = 1/2m*v2 applies to any projectile. The 10mm is far more of a .357 magnum than it is a .41 magnum. Physics.

Your question is poorly presented at best, lack any qualifications.

All these calibers are capable of equal accuracy dependent on the firearm. In a shootout accuracy is more dependent on the handler than the firearm or caliber in today's world.

As already stated case capacity is the limitation of the power (for lack of better term) when all things are equal which is rarely the case. When coupled with pressure things move.

You would be much better served by discussions on bullet construction and shoot placement as these are what actually determine the lethality of the shoot.

Yes, momentum is important only to the point that the bullet can reach the vitals. Before all the KE fan boys jump in let me point out that KE is a calculation and not a measurement and has little to no bearing on permanent wound channel size especially in typical handgun calibers.

Bottom line, choose your bullet carefully and practice, especially if plan to be in a shootout.

Where is my popcorn?

I have a copy of a page from a reloading book (somewhere, prolly in my notebook), with 10mm load data using 135 gr Nosler JHP at 1700 fps. I want to say it was using 800X, but I can't recall for sure.

A fellow that owned a strictly reloading shop was a 10mm fanatic, he was telling me about it a few years back, then backed it up by showing it to me. I asked him to make a copy of the page, then bought the 135 gr Nosler JHP and the powder, but I never followed through with loading any. I'll try and find it this evening.

Hopefully it will show what barrel length it was tested in. Most likely longer than my only 10mm (1076). I would think that load would be the tippy top for a 10mm. Unfortunately the fellow that showed it to me is no longer with us. (no, he didn't blow himself up, medical issues did him in and the shop is now closed) But I do have that copy somewhere in my records.

A 135 gr JHP at 1,700 fps should be pretty fierce.
