Getting the patent breech clean

[Bucks Co]

Some years ago I had to pull the Cherry Corners Breech from a friend's Percussion Hawken; It had been shot a lot but always cleaned religiously afterwards with hot water and oiled with 'Young's 303 Gun Oil'. The way my friend cleaned; the tip of his rod and patch could not have reached into the Patent Breech - yet it was so clean; with no tarnishing or corrosion apparent. He always cleaned as I do today with the nipple still on and a piece of tube over it to direct the water away from the woodwork. The breech had to be replaced but that was not related to the way it had been cleaned.

I have a Pedersoli Trade Gun, it also has that stupid breech. The touch hole liner came out with an allen wrench(be careful & don't strip it). Use choke tube lube when you reinstall. I used a .22 slotted cleaning jag with a small patch. I did it with the liner out so I could see that it made it all the way down. Since then, I only flush the barrel with water while the touch hole is pointing down & keep going until it runs clean. Warm sun helps dry quickly & then I follow with Ballistol. Haven't had an issue since.

Good luck.

You could take a breech scraper and grind it a little at a time to custom fit.

I modified a pump up garden sprayer that cleans every rifle I have regardless of which breech it has. It even cleans the German Jaeger with a Thovien Tige Pillar breech. Made a stand that holds the rifle with muzzle down and when the water runs clear it's clean as a whistle. With the rifle upside down any water comes out of the touch hole or nipple and doesn't get on the stock. Then dry and protect with Barricade.
Run the copper tubing to the breech and squeeze the handle, fast and easy as can be only takes a couple of minutes and done.
