i just got thru cleaning my muzzleloader after sighting in 777 powder. i found a little rust in my gun nothing bad just light spot or two, i have used bore butter for years cause it was made for muzzleloaders. i have heard recently that its not the best for a muzzleloader and if not used just right it will cause rust to form. i went to my gun shop earlier and asked them, they said absolutely to not use any regular gun products in a muzzleloader. they said to use non pretroleum cleaning products, and bore butter or a natural rust preventive. i have used barricade for years in my other guns and none have any rust issues, will it be ok after cleaning my barrel to put barricade in it to prevent rust? thanks for any help.
