I’m helping a neighbor get set up for LR. He’s got the right tools and is shooting great groups out to 300. Had him shoot my chrono so we could start cutting dope. He is not interested in handloading but we have found the factory ammo his rifle shoots best. 1- 1.25 moa ish 10 shot groups. The problem is this ammo shows a 120-130 ES on a 15 shot string (yes, with full cooling down). I don’t see that working at distance. How do you guys shoot factory ammo deal with wide ES? Throw out the highs and lows and average the rest?
