I still have a few boxes of Black Powder Express Shot high brass paper hull shells that were made for a while by Republic Metallic Cartridge Co., which I believe is now defunct. I try to carry five of them to the 1st dove shoot every year just for fun.

They certainly have the effect of drawing everyone's attention to your shooting. The rest of the shoot is dedicated to using smokeless loads to clean all that black powder fowling out of your barrels...Geo
