@agentcq:
Sure, YOU flattened a muley at 100 with a 7.62x39. You sighted him square on in a vital spot, placed the bullet right and he went down, exactly as planned.
Goes back to what Tiriaq said: training and support.
A lot of guys can't hit a flock of BARNS at 100..... and they are still out there in the field.
When I was newspapering in Nfld, the Newfie Gummint started an actual TEST for prospective hunters. Note kindly that this was the FIRST compulsory hunters' test in the country. It applied to everyone who wanted a licence: no grandfathering. Test was 10 questions on firearms safety, true or false, 7 right to pass, then 10 more on the hunting regs, true or false, 7 right to pass. There were wildlife officers present to read the test to folks who couldn't read: a good thing at that time.
Then came the shooting test.... and EVERYBODY had to do it. I took the test myself because I had written a snarky editorial about it, so I felt I had to put my money where my big mouth was. I did okay, shot it with a 1907 Mark I*** SMLE. My wife shot it with her brand-new 1943 91/30MN (which had just come in the mail and which she had never fired) and some 1950 surplus ammo. Three shots at a target 18 by 18 INCHES at FIFTY yards, TWO hits anywhere on the thing to pass. ONE OUT OF SIX DID NOT MAKE THE GRADE. Saw a guy with a 7mm RM, down flat on his belly like a reptile, great huge scope on the thing, fired 6 rounds and didn't even touch the target; his wife had an old .30-30 and she got her license, just slammed them in one after the other..... and it was only the second time she had fired a rifle!
So it's management as much as anything else. The 7.62x39 will do the job in SOME hands, but I rather don't think in all hands. That's why I discount the cartridge for most people to be using: not enough power to cripple an animal instantly if hit in a non-vital spot.
And that means that Tiriaq is right. Again.
And you can shoot.
But too many can't.
Pax?
