For flooding the barrel with solvent or wiping the bore with oil or preservatives, nothing beats a patch in a Slotted Tip. TiptonA(R) offers an assortment of four caliber range specific Rifle/Pistol tips for your convenience, or they can be purchased separately. 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.
