good enough to FACE of man at 6 ft. I got news. At 160m, the .22 rifle is down to 50 ft lbs, and at 6 ft, with the right load, the M21 has 80 ft lbs. Hey stupid, it's one or the other. either the dog is going to run for 1/4 mile plus with that .22 in his chest, or the M21 to the face is going to ROCK your world. That means, stupid, that you will be UNABLE to prevent the guy emptying the rest of the M21's 9 rds (PT22 Mag fitted, for the fingerrest's aid in control and pointing) into your head, and ONE of those pills is going to "find" your earhole, eye socket, sinus cavities, temple, base of skull, etc, and then it's going to bounce AROUND inside your skull. I realize you aint got much brain matter to scramble, but what there is IS gonna get scrambled.
