77gr smk 11.5” barrel

Yeah I had em last night, lol.
Baltic gel doesn’t shoot back either though. For the record I’m not poo-pooing gel. It as with other things has its place. Just wondering why real meat is so frowned on.

Dead meat out of the freezer is very different than living bleeding meat.

Thank you for those. Quit interesting.
I’ve seen the smk destroy coyotes though.
So much info out there to take in.

When SMK works, it works great. When it doesnt work you get what you see above, the bullet just yaws and exits out sideways. Its that inconsistency thats the problem, the SMK was just never designed for terminal performance.

Are you a real wound ballistics expert, or do you just play one on the internet?

Bro. Shooting fruit and meat and attempting to pretend its a repeatable experiment is genuinely bubba, despite how much fun it may be. And there is a consensus of professionals that agree with that, thus other positions must prove their case, not vice-versa.

Thanks, that's good to know.

What I can glean from Paul's test is distilled down to something like this,

Even from a 11.5" or 10.5" barrel, A center mass, armpit level, hit from a 77gr OTM, is most likely going to close out your health record rather fast.

Its pretty bad for your health for sure.

Ive posted here before about my experiences with M262. I was a designated marksman for my platoon in 2005 and carried a SDM-R loaded with M262 (77 SMK). I shot a guy at a map measured 400 meters +/- 10. I hit the guy low in the abdomen just below the belly button. Dropped the guy right away and he was out of the fight. He ended up abandoned by his comrades and the medic that saw him told me he had two small exit wounds in his lower back. So it did fragment at that range which should put it around 2000 FPS impact velocity. But truthfully the bullet could have hit bone and fragmented.

My team leader who later went SF told me his Mk18 and M262 was money out to past 400.

I gotta think those 77's would be devastinging our past 500. But you guys know betta

Update: I wanted to run tests to get higher velocity but with primers in short supply I kept with my current loading

Yea, pissing away primers for shits and giggles is something we used to do. Makes me ill and I'm stacked pretty deep.

I like to get empirical data from gel testing, and then use what is proven in gel on the field. From my experience shooting deer with 223/556, results are often similar to gel tests. I like having data from shooting deer, because while not all deer are the same size/construction, and shot placement is a variable, deer and humans are both thin skinned, relatively light boned creatures of similar weight. And tissue damage in real, living tissue is much different from dead meat from the store. From the several deer I've shot with it, and all the results of others, the 77gr TMK is THE best bullet for fast kills out to 400yards with the 556. From deer to black bear to elk out to say 500 yards, the TMK puts them down, and fast. Tissue damage looks like a 308. The 77gr SMK works, but in real game it fails surprisingly often, say 5 in 100 bullets icepick through. If using the SMK I try and hit the shoulder because impacting large bone helps ensure fragmentation. There are much better options than SMK, especially in short barrels. Another load I have been disappointed in the the 50gr TSX, it has performed surprisingly poorly in hogs I've seen shot, despite seemingly being a veritable deathray on paper.

Thanks for that, I think bullets on live game is a great indication of performance. But with the reloading supply chain the way it is, I am carefuly about the bullets I am expending currently.

Eh. It's a rifle. It's all gonna work for home defense...this is just like a 9mm vs 45 debate to me anymore.
