have a KNIGHT LK-93 with ss barrel, and can tell you that unless i run a wet patch then a dry one after each shot,my groups are not the same as with a fouled barrel.the more shots in between cleaning the bore will yield bad shots in my gun.i carry a murine bottle with bore cleaner and clean patches to clean the barrel after each shot.i won't leave my gun loaded overnight due to the fact that our state law requires the cap to be removed from the nipple or bore when placed in a vehicle on a public road.this allows moisture to get to the powder or pellets and when capped again,locks the moisture with the powder.this is my personal experience not something i read or heard.
