10mm Power?

er no.

Let see here...45 Super, 40 Super, and 460 Rowland for Sure, 45 Win Mag, 451 Detonics, and I am sure there are plenty others...

10mm is the cheapest and most readily available ammo wise though.

Big Boomer's right.

It is sometimes argued that the Glock 20, with sisxteen rounds of 10 mm on tap, offers more firepower than any other production semi-automatic pistol.

The 10 mm is a flexible cartridge, with a wide range of possible loadings. It can be loaded for paper targets, or medium sized game, like pigs and deer.

Overall, I think the 10 mm compares best with the traditional .357 magnum...

Lets look at Double Tap .357 Magnum & 10 mm:

1) .357 Magnum, 1600 fps, 710 ft. lbs., 125 gr Gold Dot

---10 mm, 1600 fps, 767 ft. lbs., 135 gr Nosler

2) .357 Magnum, 1400 fps, 688 ft. lbs., 158 gr Gold Dot

---10mm, 1475 fps, 750 ft. lbs, 155 gr Gold Dot

3) .357 Magnum, 1200 fps, 640 ft. lbs., 200 gr Hardcast

---10mm, 1300 fps, 750 ft. lbs., 200 gr Hardcast

I believe them's apples & apples!

Plus, there's the whole sixteen shots thingy!

Let's not forget that 10mm is just the diameter of the bullet -it's the same as .40S&W.

The muzzle energy of a bullet comes from the charge behind the bullet, plus the design and wt. of the bullet itself.

1) Well, almost. While that pesky difference between calibers and millimeters is forgiving in soft lead, the firing chamber sizes are noted to be different, and the case length of the 10 mm is considerably longer, allowing for more charge and/or bigger, heavier bullets--I don't see any 230 grain .40 S&Ws.

2) True. And the ten's specifications allow it to exceed the .40 S&W's upper limits. You're right about bullet design and other considerations--there are sectional density, gelatin tests, etc.--too.

The 10mm has about the power of a .357 Mag.

It's power has been overstated so much that I wonder if it could a defense attorney one more thing to refute.

Worse still, the hype may be keeping some from enjoying what I think is a fantastic round.

eitherway we are talking hunting rounds
un less you think a 135 grain 40 cal bullet travlin at 1600fps would be good for self defense
ps 30 bucks for 50 of um on doubletap ammo

Why wouldn't it be???

The 125 grain 357 Mag bullet at 1600 fps is THE VERY BEST one shot stopper there is...that's a well proven fact.

10 grains will increase the penetration slightly...but that's a good thing IMO. Too much is better than not enough.

Well stated. Too many people seem to want to compare the 10mm to the .41 magnum and the .357Sig to the .357 magnum.

There is no such thing as a one shot stopper. With modern bullet technology, the 158 gr. is a better performer in the .357 magnum...equal expansion, no fragmentation and much better penetration. Some people even hunt big game with 180 gr. .357's but I haven't seen any defensive loads released in that weight.

This is why I always wonder why the 610 S&W 10mm revolver was built, with 6 rounds. The N frame could have been an 8-ronder. Of course, the 627 IS an 8 round 357 Mag.

THen there are people who want to rechamber L frame revolvers to 10mm.

Well, I figure the biggest advantage of the 10mm is the Glck 20 and 29 which obsoleted the Coonan 357 and Desert Eagle 357. The feeding and easy of magazines really shines on teh 10mm which performs like the 357 mag.

There are an awful lot of dead guys that would say the 125 grain load is a pretty good one shot stopper...if they weren't, ummm... dead.

Its not hard to find the facts...if you look for them, try it sometime.

I am not saying 158-grain .357 ammo will not work in a given situation, but I played a part, with 125-grain Federal ammo, in one of the "facts" just mentioned by Ridgerunner665. I had never seen such extensive damage caused by any handgun round. The entrance wound gaped open, and stayed that way. My partner had a view from 90 degrees, seeing a very theatrical-appearing red mist effect. Then, the garden hose effect started.

That being said, I like the 10mm. I briefly owned a Glock G29, but it was too big for my hands. It is good to see 1911 pistols being offered again in 10mm. The .40 is now my agency's standard duty cartridge, and it does well against human targets. The 10mm offers enhanced performance potential over the .40 S&W.

The Desert Eagle is a joke.

10mm is the most powerful round that can be chambered in an autoloader handgun that is of a practical size and is recognized as a commercially viable cartridge. There are other rounds that beat the 10mm, but they are pretty much unicorns.

1) But give the Devil his due...

The Desert Eagle is beautiful! It is a hoot to shoot! The cartridges look like salt shakers! A well lighted range flashes blue when that sucker's fired! The muzzle blast makes your bones rattle!

2) Have to agree. But I find the variety interesting!

For reloaders, project and range guns, unicorns can be fun! For example, in the 185 grain class, the .460 Rowland is a real screamer! The 9 X 25 Dillon (a 10 mm necked down to a 9 mm) is also something else!

Glock 10mm

Can you reload, safely, for the 10mm Glock? I have a G35 in .40 S&W that I'm not supposed to reload for. I'm assuming it's the same deal with 10mm. Can anyone confirm? Thanks.

The .45 is slow and weak compared to the 10MM.

Others might disagree, but I've owned a few .45s, and never felt confident in carrying a 45 in the woods.

The mighty TEN has much more authority for wild animals or
predatory humans.

The 10mm also shoots much flatter than any 45 ACP load worth beans.

The Desert Eagle is a joke.

While I love my G20, I could hardly say that any of my Desert Eagles are a joke. I just got another DE in 50 AE a few weeks ago and right out of the box, I ran across the metal targets at our range in Jackson knocking every one of them down.

My understanding is the 10mm is the most powerful semi on the planet other than the Desert Eagle 50 is this correct?

Click to expand...

Note the OP didn't say semi-WHAT, so the sky's the limit... but assuming he meant HANDGUNS, and assuming "power" means "muzzle energy":

First off, the Desert Eagle in .44 Rem Mag is more powerful than a 10mm.

The venerable .44 AutoMag ran around 1000 ft-lbs.

The .357 Sig is maybe comparable (ties in nicely with the .357 S&W Mag/10mm discussion!)

9mm Win Mag is comparable, the 9mm Mauser close behind

9x23 Winchester is pretty hot

7.62x25 can be loaded to the moon, put Czech subgun ammo in your CZ-52 and it's like a .357 Magnum!

.221 Rem Fireball was used in the Colt's IMP as an USAF survival gun (predecessor to the Bushmaster Arm Pistol), which brings us to:

.223/5.56 NATO in many different pistol platforms

9mm Para from a long-barrelled pistol, such as a Sterling pistol or an HK94 might give 10mm a run for its money

Likewise .45 ACP from a Thompson M1927A5 pistol might use the extra barrel length to get more energy

7.62x39 from the AR pistol platform

The old .30 Carbine Universal pistol

.308/7.62 NATO from a Vector HK51 pistol just about takes the cake

I've chronographed all my DoubleTap 10mm loads, and every one of them fall short of advertised velocity. This is from both my Glock 20 and my Kimber Eclipse 5".

With that said, I just worked up a load using 800X that shoots a 155gr bullet on average of 1,550 fps for 828 ft-lbs. Like that? Thought so!

To be fair, I also like the .40. Using 800x and my Glock 35 (6"), I got 135gr bullets averaging a bit over 1,700 fps for over 870 ft-lbs. Yes, close to 900 ft-lbs from a .40 S&W. Not so short and weak, is it?

It's said by many here that the only economical way to fire a 10mm with any regularity is to reload, so it can indeed be done. What you might be concerned about is the polygonal rifling on factory Glock barrels. That type of barrel is prone to lead buildup and therefore has the possibility of dangerous overpressure so firing reloads is generally contraindicated, but there are a lot of people that do it with no issues. The warning is a "cover your ass" thing that all gun manufacturers include in an attempt to protect themselves from liability if you overcharge a round and the gun blows up in your hand, the implication being that you might not know what you're doing reloading but the factory has better quality control.

Also, the (in my opinion) overblown kB! issue with Glocks pertains to chamber support in the .40 S&W models. I don't recall ever hearing about a kB! is a 10mm Glock.

If you're concerned about that, buy a replacement barrel with the traditional lands and grooves. You can fire lead through those all day long with no problems.

Airman193SOS, the polygonal rifling issue will not affect reloads using jacketed bullets.
Yes, if you're loading lead, you need to switch over to conventionally rifled barrels, such as the excellent Lone Wolf.
However, there are some jacketed bullets that aren't much more expensive than cast lead.

Naw, not really. Mostly gun lore and internet hype. There are threads on this forum about this; you might want to do a little searching here and elsewhere. Many other forums have discussions of these tall tales. One of my favorites is http://castboolits.gunloads.com/forumdisplay.php?8-Cast-Boolits

All gun makers tell you not to shoot reloads for liability reasons. Trust me, I've been hand loading for since the early '70s and it's a common practice. Specifically, 10mm Glock 20 since 1991; 40 S&W Glock 23 since 1993. Ten of thousands of rounds later I'm just getting started.
