Most of these products were used years back when shooting bullets like TC maxi or Buffalo, Lyman and was needed as a lube and to help seal the propellant gasses in the bullets groves and probably reduce lead fouling. Now with the plastic sabots there's no need for bullet lube. Same as shooting a saboted slug from a shot gun. I still use a .10 TC lubed patch for the flint lock as this keeps from burning through the patch. BB your right about the fry pans, we have iron pans that are just as good as teflon lined ones. These are oiled after every use.
