some goodpoints. I think that when you get over 300 yds you should REALLY be careful. look at some ballistic charts, the big drop in your high power rifles occurs from 3-400yds. if you want to shoot these distances you really need to go all out. use premium bullets, they make up for poor shots to some degree. Handload - your can get more accurate higher velocity rounds by handloading, this means fewer of those poor shots mentioned before. In short, I just dont have much faith i factory ammo much past 300yds.
