....some day, I hope to manouver myself into firing my childhood "favorite" .45 "grease gun"...with the tankers' "around the corner" elbow barrel. I bet archy has one!
The ctgs. like .30 carbine and .45ACP are not so dependent upon barrel length for effectiveness. The dandy little CAR-16/15 has been reported to suffer from low velocity, and therefore "stop." The .223 bullet is very effective at high velocities because it is short, and actually tumbles after impact, veering wildly, and breaking to pieces at the cannelure...quite nasty.
Wasn't so much worried about lower velocity, I was more worried about the length of the weapon and the fact that it was way too loud for people trying to be quiet like to use even in a defensive role.
(I was on the advance party security sweep. If we ran into 'opfor' it was usually at close range and tehy usually had 'friends' nearby.)
I was thinking of the M-4 in it's specops use with the sound suppressor attached.
But, my unit, as mentioned, wasn't 'authorized' such things.
*sigh*
Was impressed with the M-249 SAW.
