I just got a Thompson Contender G2 14" barrel in .44 mag. I plan to use it for hunting whitetail but I don't know what ammo to use. Should I go for a light bullet with velocity or a big heavy one? JHP or SJHP or...? I want it to hit hard and with the very large framed gun I have I am not worried about recoil. I don't think I'll be shooting any farther than 40-50 yds, hopefully closer and I want a pass through shot with a big exit hole. Any suggestions? Thanks.
