Thanks for noticing that. I think that is a case that I had laying around from my other carbine which has not experienced extraction problems as of yet.

Can a regular gunsmith do this?

I had been thinking of having the feed ramps polished but have backed off since I was afraid removing the parkerising would hurt the value. I don't need these guns for home defense, as I have other guns that I employ in that capacity.

thanks

Hmmm...a rough chamber could make the brass stick and the extractor slip off. On the bolt, does the extractor move if you push hard on it? If it has full range of movement with a very strong spring tension and if the gripping edge looks good, it's probably okay. How about the ejector? Does it push all the way into the bolt with strong spring tension and snap out when you release it?

Swap the other bolt and try it.
Providing it head spaces ok.

Jim,
Send me four of those bolt tools. I'll get $70.00 right out to you.

Yes a good Smith can do this. You just want the chamber wall dressed a bit. If after firing the brass looks like it is frosty and has the appearance that it was rolled across 80 grit sand paper,, well the case is telling you the chamber needs a polish. It can cause drag, lag, ejection problems also.

Roger,
I did buy 4 back then. Have used two (one sitting with a broken pawl) sold one to a lady to give her husband last year for a Christmas present, and one saving for when the second pawl breaks. Need to find some of those darn things.
Don't we have any machinists here that could make and heat treat some. Might be a market for them?
Jim

I always pick up any spare pawls I can find. They are nearly as rare as hens teeth. I only have 2 of them. They usually cost about 2/3 of the price of a complete tool.
