They’re Cheddite hulls….should load up just fine using a SG16 type wad. I don’t put hardly any wad pressure when seating the wad….as soon as the wad passes the wad guide fingers on the press….I drop the shot. Should crimp just fine after that. I load 3/4 Oz shells for target 16 gauge loads.
I find that you’ll probably get 5 to 7 reloads out of each hull before you gotta trash em.

DR16 wads are next to impossible to find.
