Caliber question

[Larryjk]

I have a Hawken Half-stock 1864 I had made by a fellow that knows muzzleloaders. It is .54 caliber and really shoots well. I have used Goex, Pyrodex and Black Mag-3. Pyrodex is like shooting a flinter; never if it is going to go bang. Goex is dirty. Black Mag-3 is wonderful, but I don't believe it is available since they had the explosion last year. I have a couple others here that I want to try. Fun load is 80 grs of Goex and a patched ball. To clean up is 80 grs of Black Mag-3 and a patched ball. A 430 gr. maxi-ball and 100 grs of Goex is 14 inches low at 100 yards and hell on the shoulder if you aren't careful how you hold it.
