I purchased one of the Savage Model 11/Nikon combos from Cabela's. It is chambered in .308. I recently picked up another .35 Whelen and am strongly considering a .358Win. This model has the detachable box magazine. Aside from the new barrel and reaming the chamber, is there anything else that needs to be done? I have never owned a .358Win. and the only one I have fired was an old Savage 99(I would just about kill for that gun right now). I guess I'm just looking for any reasons why I SHOULDN'T make the change to .358. I own plenty of .308 guns and have been leaning on the 7x57 and 7mm-08 lately, so changing the Savage is no "loss", as far as no longer being a .308. Opinions? Mark W.? Spitpatch? Anyone with experience in this, please chime in. Thank you.
