Unless you really need a big bruiser like the 338 Rum, or edge or others like them Think .338-06. More than enough oomph, a lot less powder, bruised shoulders. I have a .35-06 (other wise known as the Whelen) and it throws a 225 gr. slug at 2700fps. Do you need more than that? It all depends on what you want to do with those .338 bullets.
