I am currently shooting 60gr sierras hpbt but I'm looking to go heavier. Shooting 1 in 9 223. Would like to go up to the 69gr match kings or maybe heavier again. If possible. Any experience or recomondations be greatly appreciated ☺
My 1/9 shoots the 68/69gr bullets great but will not shoot the 75gr Hornady BTHP. I never got key holes but I never could get groups from them
