Maybe I didn't read the POLL CORRECTLY, but I use loose Pyrodex in my Lyman sidelock rifles and in a Knight TK2000 shotgun. I use either Pyrodex or 777 pellets in my Knight Disc. I believe that if you are going to clean them, you might as well clean them right with hot soapy water and such no matter what you are burning. I have used lots of Goex in the past , but it is getting really hard to buy it any where here.
