I was recently given two pounds of Pyrodex CTG. It was a coarse grain Pyrodex made for black powder cartridges, and hasn't been made in probably ten years or more. Has anyone tried it in a modern inline with a shotgun primer to ignite it? I would think it might have some trouble in a sidelock, but the primer should be plenty to ignite it, just like it would ignite the powder in a cartridge.
