When I Bore Coat a barrel, I plug the bore with a Sinclair Chamber Plug and fill the bore from the muzzle with an eye dropper. I let the gun set muzzle up for a couple minutes. Then I press a piece of rubber over the muzzle and hold it muzzle down for a couple minutes. After that I set it muzzle up. Last I remove the rubber piece from the muzzle and pour the Bore Coat into a bottle. By doing it this way, I think I coat every part of the bore better.
