i havent gotten around to using my omega yet but the video that came with it i could have swore showed them using bore butter to protect the bore from rust. i will have to watch it again. i have had poor rust protecting results with bore butter.it may work but i think after a couple months it dont work as good as gun oil. the whole idea of seasoning may have some merit but i split thing down the middle. i always coat the outside metal on my muzzleloaders with gun oil. the bore gets bore butter only during the hunting season. when it gets put away for long periods in the off season it gets cleaned with hoppes and coated with gun oil inside and out.and regardless of whats in the bore i always run a couple clean patchs through before firing and sometimes will snap a cap off to clean out the petroleum residues.
