Have never used them in shotguns but have a box of 20 32/40's Dave made for me years ago, thousands of loads and no problems. RMC is very well thought of with the Single Shot rifle shooters, makes it possible to shoot many obsolete calibers. New owners from all I hear are just as good as Dave was.

I ought to order some for my 2 1/2 inch chamber Parker Hammer Gun. You did not mention powder, Black I assume ?
