I roll crimp fired paper hulls (Federal, Alcan & others). It’s somewhat of a pain to set up, but - once you have the setup - it’s pretty easy.
Beware the modern roll crimp tools - they’re really best for plastic hulls. And don’t waste your money on the BP roll crimp manual - it only covers roll crimping of plastic hulls (at least the old copy I have).
Keep your eye out on eBay for a vintage roll crimper made by Bridgeport Gun Implements (BGI). Look for one that has crimping pins that can be reversed (one way, they make a rounded roll crimp, and the other way a squarish one). I’ve seen similar Ideal crimpers in old catalogs, but have never come across one for sale. You can disassemble the tool & mount the crimping head into a cheap Harbor Freight table-top drill press. I use a BP hull vise to hold my loaded shells during the roll crimping process. I also use fiber wads to get the proper wad column. And BP sells overshot cards. You can trim the hull mouths if they get really raggedy, but that doesn’t happen for me until after a few firings. Once you trim them, you need to adjust your wad column appropriately. I also use a slick hand-held BP case trimmer. I think BP’s product name has “spin” in it.
I have seen modern roll crimping heads for sale with crimping pins in them. They may work fine on paper hulls, but I have never had the need to try them.
Good luck!
