Not wanting to kick a sleeping horse but about 50 years ago I shot a cement truck with a 1911 at 300 meters. One shot, one plink, one case of beer. Might have related that already, I forget.
On the other hand, long time back I was the owner of a 3 screw RSB that shot well enough for the occasional stunt shot. I was standing in my size 12's when this was done.
Only point I'd like to make is that it could be a fatal mistake to flip off a pistol shooter just 'cause you think you're far enough away.
