I just ordered a New Springfield (SS) LOADED M1A (1 - 11 twist) for the CMP matches at my gun club. I'm new at this and I would like to pick your brains a little if you don't mind. I just bought some 150gr. FMJBT from Horn. New WIN. Brass. And I will only be shooting 100 yds.What powder's work best in this rifle with this bullet? What would you pro's recomend I start using for the best accuracy for an amateur like me?
