Is it possible to wrongly load blackpowder into brass casings?

i wouldnt imagine you COULD even pack enough powder into a brass case to destroy a modern ruger redhawk. but i figured id ask anyway and before anyone asks the inevetable...."why" my newly cerekoted redhawk5032 has some spots that were missed. so im thinking i could fire off some black powder rounds to kind of color in the little spot near the muzzle that was missed

Filled With God

Possibly so or not


Do not load BP into brass cases unless designated for a BP gun. Why would you? I realize people do for cowboy events but just down load smokeless powder. I know you want the smoke!!
