AMMO TEST: 10mm Underwood 200 Gr Hornady XTP JHP




What do you think about this video?

SmithN' Wesson: Shot placement is key but 700 ft lbs is putting anyone down.

Jameson Cross: I wish you would use the chronograph when you shoot the bullet in the gel block. Since you only shoot one bullet I would like to know the velocity of that particular bullet.

Cephas Martin: I'm glad you did these tests. Your videos are short and to the point, but you give a lot of valuable information - information we need to make an informed decision. I just recently bought a Ruger Super Redhawk in 10mm with a 6.5 inch barrel and I'm looking for recommendations on defensive rounds. This one looks promising. Thanks.

David Sherburne: Love to have a carbine in 10 mm.

C MJ: That is a perfectly mushroomed slug. That is plenty good for defense.

C MJ: I love the 10mm. I have a 1911 in 10mm and it performs well with full house ammo.

Sam Hopkins: The first time I heard about 10mm was through a video game called Fallout 3 when I was a kid back in '08. Now that I'm old enough to buy a handgun, I'm seriously considering purchasing the Glock 20 SF in 10mm as my first handgun. Yes, I've heard the drawbacks of of owning and shooting 10mm but I couldn't care less, the power of this round is so seductive. Besides, if there are points when I get tired of shooting 10mm, I could always purchase a .40 S&W or .45 ACP conversion barrel and shoot those calibers instead.

orionh3000: fanboy of the 10mm here. thanks for the vid.

Northwest Hunter: Wouldn't this be a very good round for a self defense non-woods carry load?

Rix Pix: Dude you make the best ballistics videos on yt!

Steve Johnson: I have no doubt this round would go clean through the average man with energy to spare.
I don't worry about overpenetration but this load is a no go if you do worry about it.

Marianne Sisler: Fail

Marianne Sisler: Alllll,the "EXPERTS". So a human,has,Skin,bone, muscle, nerves. BLOOD.then,the same again. And you don't measure straight on,from right shoulder, straight to the heart

George Mezines: Thank you for a great video. At least we can get a handle of what works best for yourself and how you want to use the 10MM.

MrJumbolegz: Why did I ever bother with 9mm? What was I thinking? Lol.

John Smith: maybe the best bullet and load for woods defense in 10mm save for all but the largest predators. The XTPs don't open up too much and therefore penetrated deeply for weight, but make for a better wound than the hard casts.

maxout214226: The permanent cavity seems smaller than some 9mm you have reviewed.

Burb: I carry a G29 loaded with this ammo. Gets an average of 1145 fps and 580 fpe. Still powerful and bad news for baddies.

Sean Allyn: I kind of expected the somewhat low penetration due to the high velocity and expanding bullet, i would like to see the 200 gr. wide flat nose hard cast gas check. I know Double tap loads this at 1350 fps. I load it as well at a bit lower velocity, around 1275. this loading will go clear through a large black bear. just for the sake of comparison it would be interesting to see what that translates to in gel

Jerr Shobe: thanks for making this video

Schools: Learn how to get phlebotomy training in California! The job pays decent money for the amount of schools needed to graduate.
