As for s' question in the chat, I would not recommend taking a chance of bullet fragmentation to stave off over-penetration. I know you young fellas all think the M4 is a badazz weapon and ultra-cool but, it makes a lousy home-defense gun. I saw a lot of through and throughs in my day with this round and that was with the 55 grain bullet inside of fifty yards.
