I just had virgin valley make me a weatherby 270 cal barrel for my thompson encore. It's 26". I have never had this cal. before, and need some bullet info for it. I will be useing factory weatherby ammo because I don't reload. I live in tennessee, and will be hunting whitetails, my shots will be from 50-150 yards. I try to shoot my bucks in the front shoulders, because if they run I'm in for a long drag back up the mountain. Will the ballistic tips penatrate both front shoulders? I need input bad.
