Buddy is building a 280AI on a remington sporter profile going into an HS precision stock. My most recent builds have all been 257 and 264 calibers. If you were building a 280AI on a rem sporter profile, is there a particular barrel maker who is better than the rest for 7mm? Probably a pretty fine line, but wanted to ask. He is planning on 140 to 160 grain projectiles.
