I was going to answer here, but I forgot the name of the stuff that I use.
In the meantime, that is one of the things that we live with when shooting b-p guns. Generally, it is the stuff that on the front of the cylinder that - Tetra Gun Grease, that's it - stops the shooting. There is a limited gap between barrel and cylinder face that usually gets gummed up by the b-p residue, but that residue gets everywhere.
Bore Butter in the cylinder above the bullet usually helps to keep the residue from caking hard, and keeps it semi-soft enough to move like a sludge and will extend shooting. Bore butter on the cylinder pin though, I don't think is that good an idea. Bore butter will melt, Tetra won't melt as fast.
In war situations, the fellows that had pistols usually had swords or knives. Regular soldiers may have had pistols, but the primary weapon was the rifle or bayonet, as both made handy weapons, loaded gun or not. Reloading was probably not an option close-up when pistols were used. When you think about how long it takes to reload your gun at the range, think of how it would be when somebody was trying to kill you up close and personal.
No 'King's-X' or 'time-out' there. They probably got their 5 or 6 shots and then holstered the pistol and used something else.
Anyway, that's my take on it.
The Doc is out now.
