I came across a tub of Snow Cap lard in my basement and, being too cheap to throw it out, I developed a protocol for loading .45 Colt and .44 spl BP cartridges with it.
Charge the case with BP, insert a .060" Walters Wad, then a card wad punched from a milk carton, compress by hand with a dowel, then a measured dollop of lard using a modified aluminum measuring spoon, and finally seat a bullet on top. With the extra lube provided by the lard, I believe you could shoot these things indefinitely and not worry about fouling. Folks have also commented on the flame/fireball, even in broad daylight, so I think the remaining lard atomizes and ignites coming out of the muzzle, adding to the fireball.
