I used to shoot 20 grains of Pyrodex P. The person I had purchased it from had over powdered it and broke the pin/stock. So he had it held together with a hose clamp. I got it cheap. Shot it quite a lot. Then there was a friend of mine was just fascinated with it, and wanted to fix the pin structure. He was a very good friend who did a lot for me, so one Christmas I passed it along to him. He fixed it and hung it on a wall in his den.
