DoubleTap Penetration and expansion of various calibers.

bitches can't deal with a 10mm.

Ah yes that is true... very true... Matt?

OK what do you consider everywhere? If it can be found at Walmart I'd consider that "everywhere". But I've yet to see any 10mm there but I do find regularly there .357 Sig.

Gander, Academy, CTD, cabellas, a pawn shop, and other gun shops. Haven't looked at Walmart but then again I avoid that place whenever possible.

Guess what, it's longer! Why?! Because it isn't in an outdated archaic framed revolver! mwa hahaha! The new 10mm cartridge is in a semi auto, which allows for a larger barrel in a smaller frame with the same overall size. And that is precisely why this test is about carry weapons and self defense. If a .44 mag carry revolver was in this test, it would not put the 10mm to shame at all. Quite the opposite. Remember - I'm the same guy that made the thread praising how badass the .44 magnum cartridge is - in a full frame revolver. When it comes to compact carry weapons, it has no place.

Well, when you narrow it down to a specialized niche, then I guess it's the only place a 10mm can outshine a .44 Mag.

Sure, but I have a good feeling it's going to be quite surprising in front of my chronograph - which I hope Adam will let me do soon! My point is, in carry weapons the 10mm is better than the .44. It just doesn't do well in short barrels. However, the .44 mag is in a totally different ballpark when it comes to full frame guns, like 5"+ barrels. However, the 10mm has a special place - it's a semi auto cartridge, not a revolver cartridge. You can find full frame guns that can hold 15 rounds of 10mm - that's impressive. When it comes to semi auto the 10mm is one of the king dicks. When it comes to revolver cartridges the .44 is about 5 clicks below the top of the charts any longer. I still love the hell out of it (it's one of my favorites) but I think your opinion of the 10mm being outdated, archaic, old, and out of use is hardly the truth. I bet you in 10 years the 10mm will be considerably more popular. It's been resurging in popularity recently, and I can find it at academy, dicks sporting goods, gun ranges, etc.

I'm sure there are fans of the 10mm, but I just don't see it surpassing the .44 Mag or even the .357 Mag in popularity, availabilty, etc...

Ah yes that is true... very true... Matt?

I've shot both the 10mm and Adam's .454 Casull. I'd rather shoot the 10mm.

For those of you not familiar with DoubleTap, they are one of the few ammunition manufacturers that loads all of their rounds to nuclear/SAAMI limits. Almost all of these are max charges and the very limits of what is achievable without losing a hand. Some of those numbers are pretty impressive. Especially the 10mm showing 61% expansion on the 165gr, and 19.5" of penetration on the 200gr XTP - wow.

This brand is definitely known for 10mm. If you're not handloading and buying commercial, this would be the brand to get especially in .308/.223 for hunting...

Academy is the only one you listed I would consider to be "everywhere" and that's pushing it somewhat. Gander, CTD, Cabella's are not what I consider "everywhere" unless you happen live near one Never seen ammo at a pawn shop unless they sold guns but than again I don't frequent pawn shops to often. I wish I had a Gander's, CTD, or Cabella's near me but I don't so my main ammo supply source (other than the infrequent mail order) is Walmart which are everywhere.

look at the expansion the 9mm is getting compared to the 40 and 357.

"Best" usually depends on intended purpose, among other things.

So would you say it's impressive of the 9mm or disappointing of the .40 S&W and .357 Magnum LOL! I for one like it.

I sold all my .40 and .45 guns a couple years ago and replaced them with 9mm

It's all about velocity. Faster you get that projectile moving, the easier and better it expands. Get it going too fast (like the 135gr 10mm) and it will expand so much/fast it separates and turns into 6 petals flying through you. Those .357 rounds were just disappointing, looks like bad bullet choice honestly.
