Hoss Shoer Posted September 16 Share Posted September 16 Replacing my extractor on 73, 357/38 uberti. How much pressure should the extractor have against the case? Should it be as tight as possible or should there be some play so the spent case can move slightly? Or should it be able to wobble a lot? thanks Hoss Shoer Quote Link to comment Share on other sites More sharing options...
Flanigan Flats Posted September 16 Share Posted September 16 Probably want to minimize the movement. Quote Link to comment Share on other sites More sharing options...
Garrison Joe, SASS #60708 Posted September 16 Share Posted September 16 (edited) Pressure is only adjusted by filing some material off the arm of the extractor to thin it. Do not be trying to bend it to reduce pressure. I go by the pounds of pressure the extractor hook gives at "fully down" position. I can measure it precisely with a fishing scale and some mono line or small gauge wire caught in the groove. Pull straight up with the action mostly closed, but still have the extractor nose clearing the back of barrel. I like 4 pounds of pressure. Or, with having done extractors for years, I just put my finger tip on the nose of extractor and try to lift it. If it hurts my fingertip a little, it's tight enough. Killing my finger - too tight. With bolt out of gun, you DO NOT want any slack between the hook and edge of case rim, nor any wiggling of case, if you have the case placed between the hook and the cartridge tab and you shake the bolt up and down or side to side. Slack there, or not enough pressure, means the case has a good chance of slipping off the cartridge tab at bottom of bolt face, then bouncing around in the carrier actioninstead of being held firmly enough that the carrier block coming up can slap the case up and out of the gun. A stock extractor will probably have about 10 pounds of pressure, and will work, but many folks don't like the little bit of resistance that a tight extractor gives in the last 1/2" of bolt travel during cartridge chambering. And, I change extractors about every 3 years - just because it's a flat spring with lots of force on it. good luck, GJ Edited September 18 by Garrison Joe, SASS #60708 5 4 Quote Link to comment Share on other sites More sharing options...

Badlands Bob #61228 Posted September 17 Share Posted September 17 You'll know its time to replace the extractor because it will fail to extract a spent case and leave 6 rounds in your rifle at the most inopportune time. Usually a State match or above. 1 2 Quote Link to comment Share on other sites More sharing options...

Now Bob… it wasn’t a BAD extractor that caused you those problems… it was that dirty extractor that you got the handy dandy gadget for… remember now? 🤭 @Hoss Shoer I offer a bolt block that holds the bolt so you can remove the pin and clean underneath… over time carbon buildup can cause the extractor to become lifted and it won’t extract.

Well, with the rifle anyway. 1 1 Quote Link to comment Share on other sites More sharing options...
