I have looked all over your forums for some time now and can't find any source for new paper hulls to use with black powder in 10 gauge. Alas, I have consumed so much other useful information without yet contributing anything and feel as if I owe something back for borrowing from your extensive collective genius.
Thus my small contribution: I have tried these hulls/hull kits and found them to work. If you shoot a lot of black powder in the 10 gauge and hate the clean up of all brass hulls, this is a pretty good option. The pressure seal of the paper against the chamber wall is much tighter than brass and there is no leakage.
Just bringing it to your attention that this is available to anyone who wants a paper 10 ga hull. I roll crimp and melt wax on both the crimp above the shot and about the primer socket before assembly and can attest to it being waterproof as any of our great great grandfathers could have used for duck hunting.
