Does anyone have a source for 1X fired 10 gauge hulls? Or new ones for that matter? I can get foreign hulls from Ballistic Products. I plan to use them for 19th century black powder loads.
search engines are your friend, I would imagine that you could walk into almost any dedicated gun store and they would be able to help also. Mom and pop stores of course, not the big box superstores where the person behind the counter barely knows the difference between a shotgun and a rifle
