Cayugad pretty much summed it up, I myself use a wet patch (not dripping) but be SURE that the barrel is BONE DRY before loading or a misfire is likely and you will waste lots of time clearing out the load.Like caugad said, listen for the hissing air and make sure no liquid is spitting out either.the same applies if you use too much bore butter, it will build up in the breech plug and cause a misfire
