Blackpowder Muzzleloader Cleaning
Just wondering how you clean you reproduction muzzleloaders after taking them in the field? I used to use Thompson Center products, but as they were water based I found they caused flash rust in the barrel.
Since then I’ve been using a bore brush soaked in Butch’s Bore Shine, leaving it for 20 minutes and then running patches until the come out clean. I take out the nupple and bore screw so the excess cleaner can run out.
I then spray WD-40 into the nipple port and leave the muzzle facing down so any residue runs down the into barrel before running patches again and the follow up with a patch soaked in gun oil.
