Just had work done to my 1876 SAA by Jim Martin. I have never shot this gun mostly because it needed a lot of work. Jim made the action tight and light. I would never had thought a gun this old would never have such a nice action. The Hammer was replaced by an original first generation with a patina to match my gun. Just amazing. I spoke to Jim about shooting it. He insisted on light black powder loads with 200 grain bullets for reduced pressures. Buffalo Bore sells a light black powder load with a 200 grain bullet that is supposed to have a bullet speed of 750 fps. That is all the info they give on this cartridge. Do you think this cartridge would qualify to what Jim was talking about? I have never reloaded metallic cartridges, just shotgun. I have the equipment to do it though. What type of powder and how many grains would qualify for a light load for a 200 grain bullet?
