Molly: in the 70's I was stationed on what was then the Queen Charlotte Islands. I bought my first muzzleloader then, a T/C "Hawken" in flint igniton. The only powder I could find was Meteor 1Fg labelled "Cannon Powder". I used it as the main charge and the pan powder too, in that .50 cal rifle, and shot deer for groceries a couple times a week for three years. Now-a-days, I use GOEX 1Fg in my Sharps cartridges, though it would be great too, in a muzzleloading shotgun.
