Everythang gets tore down, cleaned, oiled, and reassembled once per year.
After every match the pistols get a hot water bath, baked at 250 fer an hour, oiled, 'n' put away. Scattergun (SxS) gets the barrels soaked in the tub. Rifle gets a patch down 'er bore, a bit of cleaner in the action, and oiled.
If'n I'd knowed cleanin up from Blackpowder waz so easy, I'd'a never messed 'round with that danged "smokeless" stuff!
