For you guys who say I would never use them, that's fine, but you put any bullet in the right spot, bt or not, and that deer is dead. I've never had trouble with a deer going down hit in the shoulder with a bt. Just about every deer I have shot with the bt's have dropped in their tracks. The others didn't go far. As for the comment "your going to lose a big buck one day for using bt's", hell that could happen with any bullet.
