I recently purchased a black powder revolver second hand from a pawn shop. It's a 44 caliber, brass framed ASM 1851Navy. I think I got fair deal on it as it only cost me $100.00 with the holster. I'm hoping it was taken good care of and not loaded with too hot of charges.It does appear that it was cleaned . I've yet to shoot it but that day is comming. I plan on keeping the loads under 20 grs.(brass!) Do you think round balls from wheel weight lead would be OK? Being second hand I didnt get the manual with it. Any suggestions on the bore size , chamber size and what size nipples. The nipples on the pistol seem to be the factory ones that originally came with the revolver. I also made a press so as not to "stretch" the frame when loading.
