Cool. I was unaware of such. Thank you. I do have an interest in reloading w/ black powder as well, I was just curious about the safety of using smokeless. I was watching a video of some survival type fella on YouTube, and he recommended (this was for a muzzle loader) equivalent charges of both powder and shot, not to exceed... 70 grains, I think it was. Does this "match powder and shot charges" hold true with reloading black powder shotshells, or was this guy just a wacko ?I don't see why it wouldn't be safe in a modern shotgun as long as you use a suitable powder for the gauge you are shooting/reloading for. Ballistic Products actually sells a manual for reloading brass shotgun shells
