just bought a brown bess musket in 76 caliber. Will be loading about 80 to 100 grains of 2f goex with a 20 mm duro felt over powder wad cut with a 20 mm arch punch purchased from Buttrans Village in the great state of Main. Plan on using ,230 round balls as that is the smallest I can cast unless I can find small bird shot somewhere. Anybody know where I could pick up some no7 or so? Also can anybody recommend the weight of shot I should load? I am thinking somewhere in the 100 grain category which is considerable lighter that the .735 ball which comes in somewhere in the 530 grain rang?
