Clays, 700X, and Unique here, 225 gr., 255 gr., and 330 gr. HP (soon), BHN ~12, cast SWC's in both 7.5" barreled Ruger Blackhawk and buffalo Classic Handi-rifle. So far, loads that function well in the Blackhawk do not obdurate well to the chamber wall in the Handi. The powder charge is not reaching its performance pressure in the Handi-. I am searching for an interchangeable "in between load" that functions well in both guns without wrist-wrenching performance from the Ruger, which to the hottest published loads is a "tame cat" to shoot all day thanks to that manageable "plow handle" of a pistol grip designed by Sturm, Ruger & Company.
