Kurt-
Intrude at will!
The little .410 hull, trimmed to two inches total length, juuuust fits the 5/16oz of shot with nitro card, felt wad, and over shot card.
A trimmed shot cup *might* fit in there, but I don't have any to try, and I don't know if there are any that are made to fit the paper case.
I do however have 1/4" felt material, punches, and loads of these pretty little paper hulls, also the 2-1/2", 1/2OZ loaded ammunition I have from the era of the hulls is loaded with a fiber wad and no shot cup.
