I never used to…and you don’t really need to…but when loading from bench I’ve developed a habit of using a stiff, small brass wire brush to wipe pan and flint between shots. Absolutely not necessary, but I’ll do it anyway as part of the routine. I guess I feel like if I’m going through all this trouble of loading, and quick ignition wanted for target shooting, I might as will try to make every effort to make sure she goes off like she supposed to.
But the brushes that come with the sets are too limp to do much good as previously mentioned.
