How much payload are you getting into the 16 ga 2 1/2 inch hull? Are you having to use multimetal wads without the cushion section? Has anyone tried cutting out the cushioning "legs" of a rem 1 18 oz wad and restacking it into the hull? Would that practice cause a pressure spike? About the best I have been able to do is 525 gr of #5 shot, and then I have remaining enough space to buffer the load and feel comfortable that the crimping will not buckle the sidewalls of the hull. Anyone using low bulk powder, etc. to realize more load volume. Give me you best shot (load data-wise) Thanks. Steve
