There was a French company some years ago selling M/L revolver cartridges made of a pellet of pressed BP glued to the base of a conical bullet. These were reviewed in a gun comic, IIRC OK but without enthusiasm.
It seemed to me that these could save quite a bit of faffing on the range, without condemning you to more at home like paper cartridges would. Dunno if they're still available, but I ain't heard tell of 'em for a while now.
