Well this is a very small operation stubblejumper, probably no more than 10-20 at a time, maybe less. Paper 10 gauge hulls are the very best for black powder reloads but they’re hard to come by. Because they only last a few reloadings I’m always looking for replacements even though they don’t get used in volume. My go to source for paper 10’s has been vintage Canucks and Maxums at gun shows but they’re getting very scarce now. This high quality Scottish ammo landed in my lap, I’ve only fired a dozen or so at this point but I don’t want to waste the hulls without a serious effort reuse them. My time is not an issue, the luxury of retirement.
The other thing to be aware of, is that those 57 primers seemed to have issues in the cold with certain powders.
