I have magnum primers and 3 powders. I cant get LR primers in, all I have is my LRM primers. I have IMR 4350, H414, and H4895. What would be a good load for an M1A with a 20 inch 1 in 11" twist, medium duty Krieger barrel. I am trying to work up an accuracy load for competition. I could sure use some help as it is for my teammates gun, and if his gun shoots crappy, we are doomed. Thanks in advance.
