ok this may be a stupid question but why can't you shoot smokless equevelant loads in a cap and ball blackpowder pistols. for instance if you can shoot 3.0 to 3.2 grains of bullseye for 700 to 750 fps in a 38 special, which is a load that developes about 18,000 psi and 30 grains of black powder developes 25,000 psi in a 36 cal. cap and ball pistol at about the same fps. what would stop you from using smokless in a blackpowder gun????
