True enough, but I know plenty of beasties who've upped and ran from a 556 round or two, much to the chagrin of the shooter. I also know this 7.62X39 has rather poor wound tumbling/breakage and being that coyotes are not very wide, the bullet might go right through, wounding, rather than assuring a kill shot. That was one of the complaints in Nam about the 7.62X39, is you would shoot a man in any non vital area, he was liable to get up and get away if you were not fast enough. Sounds like it is a good target for bigger, meatier targets like elk or deer where the round can decelerate enough and have at least 30 cm of entrance length to yaw properly in the body cavity. Just my 2 cents.
