Still havent tried my hand at rolling paper cartridges yet. Dont know if ill ever get the time. All aspects of our "hobby" are equally time consuming. Likely, I've spent more time learning, reading, making things myself, and developing skills, than I do actually shooting, and i shoot too much....
Still, even though i havent gotten around to trying it, paper cartridges are just neat... nice job.
