Hell for stout, penetrate like a fine stud horse, plenty accurate, they break bone no doubt. I'm sure I'll use them again in the future but I'm going back to partitions, ballistic tips, accubonds, grand slams and interlocks for now. Might just be my luck with ttsx but if I don't break enough bone to anchor deer quickly I end up wading through "Hell's Thicket's". That can happen with any bullet every day but a lead mushroom seems to knock them off their feet right now. Just my two cents.
