RE: .338 mag
I have killed many deer with the 338 using anything from 200 gr BT to 250 grandslam bullets. I just loaded 180 gr Nosler accubond for my dad and I think they will work well, Bottom line they all do damage but you will have much more with the more fragile lower gr .. If you are worried about damage use a tough high gr bullet such as the tbbc or the x bullet ..
