I was just curious about members opinions of the 220 Swift caliber. I have a Ruger M77 Mark2 chambered in the 220 Swift. I originally wanted the 22-250 or 223, but the only caliber available at that time was the 220 Swift. The gun shoots nice. Beautiful gun with a nice big fat barrel. A lot of weight to the gun. I have read that the 220 Swift wears out the barrels fast. Any truth to that? If so, what should I be looking for and what steps should I take to minimize the wear?
