of course it doesn't, to some ignoramus
but it sure does to anyone who KNOWS anything. You "think" that just because a hit with aheavy .45 Colt load will EVENTUALLY result in an anima''s being bled out (10 seconds or more) means it's an effective manstopper.
Hey dummy, when a man's trying to kill you, anything beyond 1 second, in the way of an "instant" stop is pretty worthless (at handgun ranges) what's needed is something to make his arms fall to his sides, or freeze in place, in 1/4 second or less. The 223 sp has MANY times proven its ability to do this, at LEAST as often as does a blast of 00 buckshot. Yes, 223 sp can fail, so can 00, but it's a 1 in 50-1 in 100 RARITY, not a 1 in 3 commonplace event like .45 ball's failure(assuming chest hits with all of these loads)
So I set out to find-create a load that would be as controlable in an alloy, compact ccw gun, as .45 ball is, with as close to 223 softpoint (in a RIFLE) type performance, (on flesh and blood) as was possible to attain. After much searching, I hit upon the 460 Rowland case, the 3 segment Split Nose" prefrag hollowpoint, with its huge, deep hollowbase. 70 grs, 2300 fps, in a 4" barrel, and it enables one to get .18 second splits, or faster, just like .45 ball ammo does, in such a gun (ie, 28 oz lw Commander). It has 800 ft lbs, transers it ALL in 8-
10" of flesh, and it rarely fails to penetrate deeply enough, and has yet to fail to create 3 separte wound channels, in the shooting of many animals with it. It has the same effect on large dogs as does a shorty 223 at 50m,or a 20" 223 at 100m or so. That is, they are knocked on their butts, and can't regain their feet, and they die in a very few seconds.
Given the "cumlative overload" of tissue destruction and shock, and the ability of a skilled, "cold" man to put 3 such rds on the chest of a man in .50 second, I'd say that they are as likely to suffice as is a blast of 00 buck, and one such hit is a LOT more likely to suffice than is any 250 gr swc .45, at 1000 fps.
