I finally got a round ball mould for my .72 Pedersoli Kodiak. The balls measure .705 which is .010 less than what most people shoot from these. I was shooting it with a .015 patch and trhe results were OK. Not spectacular , but OK. I ordered two things for this gun. The first are .020 lubed patches to give me a little tighter fit. I think this will close the groups up a bit. The second thing I ordered is a conical mold from Brooks Moulds. This will give me a solid lead slug that weighs in at 770 grains. This should be punishing at both ends. Conicals get mixed reviews when fired from a Kodiak double. I always thought that for the heavier round, much more powder should be used, but the best results that I have read about have been around 100 grains of BP. I will be using Triple Seven BP substitute. I will be starting with about 80 - 90 grains. This should be a good start. Wish me luck.
