Thanks Jimy.
After my first dive into the deep end several thoughts come to mind. The brass is ballpark 2-5/8” OAL and in general terms uses wads one gauge larger for loading. That said, it seems to me that any case, paper or plastic, could be loaded in the same fashion with same gauge wads. All that would be necessary is to trim the crimp segment or use a press to crimp the case. Black or smokeless? How new is the steel in your barrel? The base wad incorporated in paper and plastic shells will change load internal geometry. With the brass and loads I’ve assembled there is about 1/2” of empty case remaining. Doubt that would occur with paper/plastic hulls. OTOH, all of my scatterguns have 2-3/4” chambers. New kids on the block are likely playing with 3” chambers.
