Lance: the penetration tests I've seen indicate birdshot is not able to reliably reach the vitals (especially through an intervening arm etc) outside of near contact range. Do you have evidence or life experience that contradicts this?
I had a friend who had the better part of his head blown off in a range accident about 30 years ago, about 5 yards. It was birdshot, not sure what size though. But at that short distance the shot is coming out in a near solid pattern.
I've seen so many threads where people say it isn't effective. I know different.
