I just dug out of the safe, my T/C Hawken 45 cal cap lock rifle. I bought it new in the mid 1970's. Hardly ever shot. I haven't shot it in years until this week. I have some 3F powder and Pyrodex, with T/C Maxiball and .440 RB projectiles. I am going to need some percussion caps soon. Are the magnum caps better, or intended for the BP substitutes? I have tried 2F, 3F, and Pyrodex in this rifle. It seems that the BP out performs the Pyrodex for accuracy, and the 3F shoots a little better, with less fouling than the 2F does.
