Ive got a .308 Ultra and it's a shooter, too. I haven't done any specific load development for it, but it likes my standard .308 load of Reloder 15 powder and a 168 GameKing. It'll shoot it under 2 inches, hot barrel or cold, long string or short, it does it with boring regularity. If I did any specific load development for the rifle, it might start shooting one-hole groups. THEN what would I have to complain about?
