Pedersoli Kentucky Rifle Rust

[fishmusic]

I have a Pedersoli Kentucky Rifle flinter in .45 and have owed it for about 4 years. While I am a meticulous cleaner there are rust spots where the breech seals in the inside of the barrel. I noticed them while cleaning the gun after shooting. Naturally my concern is that eventually this will get to the threads of the breech but right now it is minor and I want to stop this before it gets worse. I have tried using steel wool on a jag but it doesn't get to the very edged where the rust shows up. My bore scope is cheap and doesn't have a way to capture pics or I would attach them.

Dare I drop some rust dissolver down there to get rid of it? I don't want to ruin the barrel. Any recommendations?

Ah, the joys of the patent breech. (not a fan). I have same rifle in .50. Employ a bore caliber breech scraper and sub-caliber brush to get into the breech channel followed by penetrating oil then repeat after a few days and see what comes out?

Rust is like cancer: if you don't get it early, you have a problem.

The rust is not in the chamber, it is where the breech meets the bore. I will take you advice about the scraper for that interface. I agree that the "patent breech" is a royal pain. This one is not unlike the CVA breeches where the touch hole liner is threaded into the breech plug. Removal and cleaning is not an option.

Something like Evaporust would not ruin the barrel but it could remove the bluing if you're not careful.

Evaporust, like mentioned above, don’t get it on bluing, just in the bore. It’s very safe in every other way and works GREAT, then lube the heck out of it.
