Gary instead of locktie I use TC breach plug grease, it works so far...
Yes Gary, I use it for my muzzleloader, it got that bluish/greenish color as far a description TC posted next: "A synthetic based lube that withstands the high operating temperatures of muzzleloaders to prevent fouling residue from binding breech plugs. Also works well on nipples and shotgun choke tubes. "
i have heard that shilen barrels that have been coming with tool marks in them.
