A few weeks back I had the great fortune to get to shoot a $5500+ police sniper rifle topped with a $2200 Nightforce scope. Now I have the bug to get a bolt gun to get me started on learning how to "reach out and touch something." I am thinking something like a Remington 700. I'm not a hunter nor am I interested in competition shooting. I'd just like to be able to punch holes in cardboard or pumpkins at ranges of 300-500 yards or so. Any thoughts on .308 vs. .270? 25-06, 22-250, .243? Any thoughts on Savage Arms or Ruger Gunsite Scout rifle? Other brands? Thanks.
