Is my Lyman Deerstalker a patent breech?

[Canuck Bob]

I've been studying and finally realized what a patent breech is. Do the Lyman products use them?

If they do I understand there is a cleaning issue with the reduced area of the breech. I'm assuming that is what the scrapers are for. How do ypu know the shape of the breech profile? I saw a picture of a split wooden dowel with a scrap of rag used to clean the breech, struck me as a good idea, comments?

Yes, Lyman rifles have a patent breech. If you look down the bore with a good light, you can see the shoulder.

I use a .36 cal brush to clean the patent breech on my GPR. Another idea is to use a .22 cal brush with a patch wrapped around it.

I've had my .54 GPR pecussion for over 30 years. Never did any special cleaning to the powder chamber in the breech and never had a problem. Just clean the barrel with warm soapy water and it will flush all the crud out of there. I use Ballistol oil for patch lube and don't have to swab between shots, which can push a lot of crud down into the breech. Been doing my .54 GPR flinter the same way with no problems :thumbsup:

I went so far as grinding a scraper to fit, but lost it somewhere. Never felt like going to the trouble of grinding another. Been using a 35 cal brush ever since, wrapping a patch around it for final wipes, drying and oiling. No sweat at all. Could probably get away without it because I flush the barrels, but habits are hard to break.

Ditto, same with a TC Hawkin. If you bump your cleaning patch hard against the shoulder it will sometimes leave an imprint of the shoulder and even cut the patch a bit.

I know some guys use special tools for cleaning this area and it's probably a good Idea but for me it has not seemed necessary.

Since I already have a .32, I run a .32 cleaning jag down inside the patent breech first. Use an 3 x 3" cleaning patch so that it stays on the jag, single layer. Then I clean the rest of the barrel with the .54 jag. Works great.

That's what I do with my GPR. .22 cal brush with a patch wrapped around it.

I have a .54. Soap and water to clean. When i have followed up with the scraper it comes out clean. Guess the soap and water are sufficient.
