While an 06 will do just about anything you need it to... for myself, I have found I really don't need it... where lighter calibers will do the same job...with less recoil

which has given me the opportunity to play with and adopt older traditional calibers...

If I stayed with one case type only, it would be based on the old 57 mm Mauser case... 6mm Rem, 6.5 x 57, and 7 x 57 will cover my non varmint hunting needs just fine..
