10mm Kills

[Micneador]

In all my 10mm crap postings(as well as owning 4 different 10mm chambered weapons), I've yet to kill a deer with that Caliber. Anybody on here actually killed a deer with the 10mm? If so please post pics especially if they contain entry/exit holes and include what bullet you used. I have a 10mm CMMG Banshee AR that has produced some promising groups with 180 grain XTP hand loads @ 100 yards. I carry it more for hogs but I won't pass up a doe come this holiday antleress season.


I smacked a young female coyote with my S&W M&P10 the other day with doubletap ammo 200 grain hard cast. 10 yards straight on and I was kind of disappointed I didn't get a pass through.

No kills with mine yet but I have thought about trying to get a deer with it this season. Maybe a big boar will volunteer. I'm amazed the 200 grain hardcast didn't make it through a young coyote. During load workup over the summer, I was shooting through 14 inches of dense wetpack with a 200 grain hardcast at 1200 fps. That will normally stop a 30-06 soft point.

I mean unless it came out of either holes of her backside perfectly, I didn't see an exit.

That’s a good bullet. I’ve taken a few deer with the 35 caliber 180 XTP out of a 357 Herrett and 357 Max. One went through the shoulder on a 200lb buck no problem (~1800 fps at impact)

I picked up a Glock 10mm this summer in hopes to hunt with it this fall, I wanted to be accurate with it to 50 yards max. I grouped really well to 25 and that was it. Decided not to take it since I couldn’t reach 50. I’m waiting on a red dot sight to come in the mail in hopes the accuracy will improve. As far as just shooting 10mm, I love the cartridge. I love that xtp bullet too. I’ve reloaded it with 40 (before I got a 10mm), 9mm, 350L, and 44 mag. All have been accurate and the performance on the 44 mag (rifle) last season on a shot over 120 yards was very impressive.

I thought no pass thru was a good thing with a bullet? Means it opened up, and the cavity was absorbing the energy?

I'm not doubting your results. Bullets do weird things. My friend had a Barnes TSX from a 35 Whelen make the exit you are taking about. He shot it facing him at about 60 yards. We looked everywhere for the exit and then finally realized the bullet came out the EXIT! What's the term? "Nothing but net?" I felt bad for that buck.

The idea of hardcast is deep straight line penetration on tough animals. Sort of like using a solid for dangerous game. They are meant to not deform.

I flat point bullet will cause significant tissue damage due to tissue displacement perpendicular to the meplat, the flat striking edge of the projectile. Liquids are virtually incompressible under ordinary circumstances. Living tissue is about 70% water. As a flat nosed bullet travels through tissue above a certain speed (my guess is the speed of sound), water in the tissue in front of the bullet is displaced off the flat face of the projectile perpendicular to the bullets travel. This creates a hydraulic pulping effect to the surrounding tissue. Both Elmer Keith and Veral Smith go into fairly lengthy detail about this phenomenon.

He was referring to a hardcast which shouldn’t open up. It is possible that a bone was hit and it could have deformed the nose causing more drag. But generally I agree it should slide end to end on a coyote. I have heard the double taps are loaded a little lighter than others like underwood or Buffalo boar, but that shouldn’t significantly affect performance on the coyote.

I picked up a G40 this summer can get 4-6” at 50 yards with a red dot. Even with my astigmatism it helps accuracy. I’m still trying ro score with the 10mm.

This is from Veral Smith's Jacketed Performance with Cast Bullets, Pg. 102. It describes the pulping effect of a flat nose bullet. A book I can highly recommend, along with Elmer Keith's Sixguns.

I actually had one instance a few years back where I should have killed a doe with it but I had my kimber in my pack, in an uncle Mike holster, and had the strap snapped on. Never Unstrapped it when I got in the tree.

Had a Glock 20 and killed a few critters with it. Exit wounds aren’t very reliable but that’s the case with many handgun/muzzleloader projectiles. There’s not many cartridges I think are much fun to practice with that are adequate for hunting but the 10mm is one of them.

I didn’t think I’d find a 10mm kill on my phone but I managed one. It was my profile on the Handgunhunt forum about two decades ago. It was a little Cumberland island buck. Shot it in the neck looking back at me at 45 yards after missing it with a scoped contender pistol in 30-30 at like 25 yards. My first big game handgun kill.
