Do this ^^ Works for me on a Pietta Remington .44 - although I use more than a little, enough to stop ingress. Copper grease is temperature resistant so won't run when it gets hot.

I've also found that using grease cookies between wad and ball softens the BP residue and reduces the fouling. I've never found mashing a load of lard over the front of the cylinder has reduced fouling - most of it isn't there after the first shot anyway. Most days I run out of range time before fouling becomes an issue - and using the cookies means the pistol is pretty much wipe clean afterwards. No scrubbing / hot water / dish washer required
