Shadow1198 Some of you guys make me laugh. It is a physical impossibility for nylon to wear away at a STEEL barrel UNLESS it's under a severe amount of force/pressure.
Then explain why fishing rod guides are now mostly made of ceramic? The old STEEL
guides would be grooved by the nylon line,(monofilament).
Here's my method; A one piece mylar coated rod, used WITH a bore guide, cleaned from the breech, using phosphor bronze brushes and caliber specific jags/patches. A good solvent of your choice,(I use wipeout), followed by lightly oiling.
More rifles have been damaged by improper cleaning than by leaving them dirty. Modern fire arms just don't need to be cleaned as often as most people do.
