Last summer I started shooting a .270, a Cooper model 52 Custom Classic, a standard weight sporter. Using a Zeiss Conquest, 4-14 and 135 grain SMK's. I'm getting 2910 fps and according to Sierra's data the bullets have a BC of .488. I have been shooting marmots out as far as 749 yards from a bipod. I didn't shoot just one, my total take for the two weekends I got out were 7 at ranges from 600 to 749. I'm not sure how much more elevation I'm going to get out of the scope with the standard Talley rings and bases, but I intend to keep extending the range until I run out. At that point I'll have to do something to build in more elevation. I have shot this rifle only as far as 550 yards on paper, but I'm getting .4 moa accuracy out there. I believe I could shoot coyotes out at 1K with a little more elevation in my scope mounts, and the addition of a sand bag at the butt of the rifle. May need to lighten the trigger a bit too. Right now it's at 3# as the rifle is set to hunt big game.
