PP Bullets in a Tube Magazine Rifle?

[Flash Pan Dan]

Thank you for your responses. Because of the unusually long barrel, I’m concerned that I may know have enough lube in a lube cookie to prevent fouling issues using black powder, though black powder would be my preference. I have had good results with H4831sc in my 45-75 Winchester. It fills the case but leaves a lot of unburned powder. So I am also at a quandary as to what bulk smokeless powder to use.
