Seems that seasoning has tweaked out the squealers. Vegetable grease like Crisco yellow melted into patches can be used to both clean and preserve the inside of a muzzleloader barrel. A bit more work but I store my Black powder guns with a thick coat of Crisco or vegetable oil. Yes it is a bit of a chore to remove after it sits for a year or so but when you get it out there will be no corrosion. Hot water and dishwashing detergent is your friend. I have used Mr. Clean, Awsome orange, windex, Ballistol to initially clean my rifles along with hot water and dishwashing detergent. None of my barrels have any rust or pits in them. I have had my 50 and 54 caliber Renegades going on 30 years and they are still fine shooters. When I did a lot of black powder matches I would often soak the inside of my barrels with transmission fluid on patches and do a deep clean when I got home and never an issue.
