RE: Two Questions Caliber and Scope
.270 is great as is .308. I'd prefer the .308 but that's just me. Either will certainly do. As far as scopes, I like Leupys, but there are many other very good brands out there at reasonable prices. To name a few... Zeiss Conquest, Sightron Big Sky, Burris Fullfield II, Bushnell Elite 4200 and Weaver Grand Slam. Good luck in your selection.
