Thread: Crimping and it's effect on accuracy.

poohseventy shooting 3/4" now.......DONT CHANGE A THING..... one thing to try (if you dont do it already) as you are seating projectile rotate case 180ish degrees and continue seating projectile,by turning it you conteract any runout tendency of the press....had many try this then measure it with good results,as for crimping,it MIGHT improove ES by controlling burn but not something I would muck around with myself.
