For flooding the barrel with solvent or wiping the bore with oil or preservatives, nothing beats a patch in a Slotted Tip. Tipton offers an assortment of caliber range specific Rifle/Pistol/Shotgun tips. Solid brass is softer than barrel steel so there is no worry of damaging your bore, plus they will last much longer than the typical synthetic plastic tips. Rifle/Pistol Tips are threaded 8-32 and the Shotgun Tip 5/16"-27.
