A .300 Wby Mag is quite a bit of gun. Even for elk. If you don' t mind getting knocked into the next county every time you squeeze the trigger, go for it.
I think a .280 Rem or a .270 Win would better suit your needs.
LOL...
I agree with seattle. The big guns are fine if that' s what you really want, but the .280 or .270 will probably do all you' ll ever need.
