RE: Pyrodex Pistol Powder
I've even found that the 3fg cut of 777 works well in rifles too. And you don't really have to cut the powder load with it either, since both cuts of 777 are very fine - not much difference except that the 3fg seems a tad more consistent.
But ............. it seems to work best with heavier sabots - bullets 300gr or less or ANY PowerBelt shoot better with the 2fg out of my Knight.
