I've been using the MagTech 2 1/2" brass hulls for the 16g with 60grs (by volume) of 2F and 1 oz of shot using fiber and overshot cards and Elemer's wood glue to seal the mouth. I've been using plasticfor the 10 and the I. Hollis gets 60grs of 2f or coarser
also with fiber wads and those are roll crimped.
The 10g loads for my modern hammerless double is 120grs of 2F or coarser and 1 1/2 oz of shot. When I light that off, everybody notices and sometimes I fire both barrels at once. Inside and around the some of the building props both barrels at once is.........rather noticeable
