Ok first of all I developed asthma and being winter in WI I don't want to cast inside.
I just bought a 1858 Remington and have a 45 Colt/ Scofield cylinder coming. I did a search and cast bullets at the normal places are non existent. So I bought 2 boxes of Speer .454 Round Balls.
So I need some recipes for cowboy type loads under 850 fps. Powder on hand is Unique and 2100.
