I just purchased a 121 fieldmaster that was manufactured in 1949. When I first got the gun it would not load a round. I broke it down and cleaned it up real good, then it would load and eject so I took it to the range.

First shot and the empty would not extract, I had to pry it out. Several more shoots and the same thing. Brought it home and cleaned some more and the same thing happened. But I had some .22 long 710 fps with me so I tried them and they would extract and eject.

Brought it home and cleaned it some more, went back to the range and the same thing. I started with long rifles 1200? fps and they wouldn't extract, went to longs 710 fps and they extracted. After I shot 50 rounds of longs I tried another long rifle and it extracted and ejected. Tried a few more no problems, went through 2 magazines of long rifles and 95 percent extracted and ejected so I figured problem solved.

Brought the gun home cleaned it real good, next time I went to the range, same thing all over. It will extract and eject longs and shorts, but not long rifles, they stay stuck in the chamber.

I have been told that maybe it was dry fired a lot and has burrs., but I don't see any, and I lightly touched a file up around the edges of the chamber any way. The edge of the chamber does have a few nicks at about 12 o clock.

I have also been told that maybe the previous owners shot a lot of shorts and the chamber just needs scrubbed real good. I put a bronze brush on a cleaning rod soaked it in hopps 9 and the other end on my foredom and went in and out of the first 3/4 to a inch of the chamber and scrubbed it down real good.

I still get the same thing 99 percent of all shorts and longs extract and eject. Only about 5 percent of all long rifles will extract and eject. sometimes if I just have one round loaded when it gets stuck, I can rack it back 3 or 4 times and it may grab it and pull it out and eject it.

So what do you think, do I need to keep scrubbing? do I have bore damage? maybe my extractor is week? what do you think. I really like this rifle and I want to hang on to it, but I want a gun I can shoot.

I just bought a 22 chamber iron from Brownells to try on it next week.

Please help, Thanks Steve

Welcome to the Remington Owners Forum Steve...!!

Sounds like you may have a bad extractor...take it to a gunsmith for a checkup / and or a new extractor.

Remember...the gun is from 1949 !!

A chamber iron fixed my issue.

Good to know...thanks for sharing the fix !
