Just getting into the hoby of shooting Black Powder cartredges. Seems to be alot of variations in loads out there. I am looking for anyone who can help with a load for a .45 colt ( lead 230 gr rcbs cowboy mold # 82308) and .38 spec. (lead 140 Gr. rcbs mold # 82304). FFF or FF Black Powder? And what about fiber fillers? use or not? Thanks for any help. Any reccomended books on the subject.
