A good place to start is with the same number of grains as the caliber, .45 cal = 45 grains, .50 cal = 50 grains etc Those are safe loads, and generally good for plinking. If you are looking to hunt or long range shoot (over 50 yards) then you can go up from there to find the load that works best. Step up in 5 grain increments and shoot 3 rounds each until your groups come together. I would not recommend going over the 100 grain mark with any gun unless it is marked on the barrel as a magnum, contrary to popular belief you can overload a black powder gun with deadly results. Also the gun you have was made in February of 1992, the number you listed is the serial number, they did not have a model number.
