I got this rifle used in a trade and its an outstanding rifle, however after about 500 rounds it started developing an extraction issue. I tried cleaning the chamber and making sure there wasn't any debri, which is hard considering the size of the chamber. However as far as I can tell so far there isn't anything in the chamber that shouldn't be. I chalked it up to the 6 cent a round ammo as it never had an issue with other ammo and this was the third or fourth ammo type I tried through the rifle. However now it is not extracting anything. I can run anything into the chamber and it seems like the extractor itself isn't grabbing the rim. I can easily slide the cases out if I can find something to grab the rim with. So I took a look at the bolt and the extractor looks like its sitting low. The cases I have the thickness of the rim is about .040 and the cut in the bolt for the case head is about .043 deep and I can slide a case into the bolt but the extractor doesn't hook it. I'm curious why the extractor would have moved back. Trying to upload a photo but it isn't working out right now.
