in order to stop men,pretty pointless to shoot them with a 357 snubby, with its 16 factor momentum,eh? If 357's 16 factor momentum is adequate at axe swinging ranges,why aint the 223's 16 factor adequate, at 400 yds? 75 gr v max, 24" barrel, still has 2000 fps left at 400 yds, and that's a 16 factor momentum,and that sp will still expand. A 125 gr 357, at 1250 fps from a snubby barrel, aint all THAT likely to expand much at all in flesh, actually. A failure to stop, at 10 ft and less,is a LOT more dangerous to the defender than a failure to stop at 400 yds. At 400 yds, the guy can't do CRAP to you, after taking a fairly good lick to the chest. He CAN do so, however, at 10 ft. He can be all OVER you,in 1 second flat, standing start, from 10 ft away, and MOST handgun defensive shootings will be at SIX feet or less,where he can reach you in .5 second, and is PROBABLY already charging BEFORE you fire. At 6 ft and less, ANY shot he fires is HIGHLY likely to hit you. Wounded, at 370m, he can fire a truckload of ammo, and never touch you, if you have sense enough to be head on prone to him, which you had to be in order to hit him in the first place.
