I have a 270 sauer, its not very fussy, and shoots most things well, I tend to use 130 gn, or 140 homeloads, federal power shock shop bought. with sierra matchking 130 , i have played about and gone out to 600yds on a range, its as still good as an avarage 308 at that range , but sporter barrels warm up, and a group will widen, but about a 150-200mm at that range is pretty good. good luck
