I bought my 1875 Remington (Uberti) in 1975, and until recently, it has only known black powder. My load is 30 grains of 3Fg GOEX and a 255 grain bullet. It shoots right to the sights at 20 yards...oh, I replaced the little factory sight since the new revolver shot so high, with one that resembles a SAA Colt. It is thin, to match the rear notch, but is deadly accurate, and has won me a lot of honours. I see now that the new ones come with a better front sight. I automatically give it a quick cleaning now, between stages, and it continues to perform well.
