Picture of the Chamber
View from straight behind.
Red box shows the damaged area.
This is a blow up of the area highlighted by the red box in previous picture. The color has been inverted and the contrast increased to show extent of damage.
My question is, what is the best way to fix this? The rifle is a Stevens Model 66-B chambered for .22 short, long, and long rifle. My father bought it used about ten or so years ago, and it has had problems with extraction since then. The chamber seems to have been slightly damaged by the firing pin, probably due to dry firing. It appears that the firing pin has made a dent in the chamber wall, which in turn forced a small amount of metal into the chamber opening.
I can only speculate that the extraction problems are caused by the fired cartridge casing hanging up on the damaged part of the chamber. I asked someone at a gun store what the best way to fix this was and they said to take a file to it and remove the portion that is sticking out into the chamber. Is this the recommended method? And if so what type of file should I use?
