I wouldn’t buy them. No telling what a prosecuting attorney would tell a jury. On the other hand, as far as penetration, a cement block didn’t stop them.
Excellent point. An anti gun attorney or DA would have a field day proving you set ou to kill with these gimmik rounds. I forgot where I got the advice but I heard it is best to use the same rounds the local police forces use. Then the DA can’t claim you’re using some extra lethal round.
