I recently picked up a sporterized mauser in 30-06 cal. Did some looking and what i found said sears imported and sportered a bunch of these in the 20's. From what ive read they are bullet hoses. The barrel is .311 vs the .308 bullet. What would you guys do with this rifle? Im looking for some ideas, i just bought it for the action basically, but i also worry about destroying historically valuable guns.
