I love the 300WM and similar, I personally think they give you an edge with good bullets. From near (lots of power/penetration) to far (easier to hit with, again with power.) While I know lots of guys who use smaller calibers on big game, I "like" how a big gun works on big animals, especially with a less than perfect shot. I tell guys just use a rifle style/weight/handling that you are comfortable with and go for it! A 308 Norma with todays powders, shucks, you are Gold! Have fun pard.
