A device for a bore wiping, self-lubricating ramrod used for muzzle loading gun barrels. The device consists of a bullet jag with two O-rings, and a center hole to allow the lubricant to get into the bore. As the jag is passed down the bore a small amount of lubricant is released into the bore. The first O-ring stops the lubricant from leaving the bore, and the second O-ring wipes the bore clean when the ramrod is pulled out of the bore. The ramrod may be made in different diameters to accommodate different caliber muzzleloaders. The shooter uses the same ramrod for lubing and loading the weapon with the same pass down the barrel.
