.45 Schofield Black Powder, (substitute APP) loads seem to work exceptionally well in my .45 Colt 7.5' Calvary SAA Model.(made by Pietta) At the recent Muster at the Searsboro Range in Iowa hosted by Whiskey Double and Sam Perfye, I cleaned the 5 plate rack at bout 21 yards with 5 shots.(windy, 2 handed) Later in Precision Pistol I scored 94, which I think is my personal best in a match. Also about 21 yards, 2 handed. I'm in the process of removing the smokeless lube from some 200 grain bullets to relube and try with Old Eynsford powder.
