it does help, thanks I used the Steyrclub how-to on cleaning the extractor, it wasn't overly dirty after about 200 rounds. I also noticed that the spring end thing doesn't look like the one in the manual that had a notch in it; mine is a rounded tip like a dome that pushes on the extractor. Not a big deal, just something I noticed. I'll see how it fires next time I shoot and report back.Dag said:Hi BTF/PTM
Debris building up behind the extractor hook is one possible source. Extractor spring problems (weak or broken spring) can contribute. I suspect some issues with the chamber could be part of the problem, if the chamber has burrs or tool marks that inhibit the fired cartridge from sliding out of the chamber. The extractor hook has to cleanly slip over the new round as it's stripped off the magazine, it has to firmly grip the fired case to pull it out of the chamber, and it has to release the case at exactly the right point, when the ejector strikes the case rim. It's a complex mechanical process that has to happen quickly and under great mechanical stress. Everything has to be just right, and it doesn't take much to muck it up. Firing several hundred rounds helps seat all the moving parts, including the extractor, and extraction problems will frequently go away with a few hundred rounds down range. Hope this helps.
