is there published data for swiss and goex for PRB? I shoot a 40 cal. flintlock and swiss 3f is what I use because its what I have. I am getting best groups with 40gr. .395 RB and .018 pillow ticking. I have went up to 55gr. but groups open up a bit. just curious if there is any published data on different powder and calibers,,,,,,,,,,,
