I cant imagine a deer going very far with a well placed shot from a 300. By well placed i mean heart/lungs, neck, shoulder, head. Maybe if the deer was gutshot he would go a ways, but that has nothing to do with the cartridge. I meant the fusion bullets i shot deer with didnt expand as well as the ballistic tips. I would not be afraid to shoot any game animal on the north american continent with a 165 grain ballistic tip from my 300 wsm.
