[QUOTE="screamrider, post: 1065276, member: 52942"] Really appreciate your help Bill! Looks like I may have just pinpointed the problem. I tried chambering some of the twice fired federal cases I was using and noticed some excessive friction just prior to ejection (going very slowly). After playing with several pieces of brass and working the bolt back and forth so that the shoulder was continuously rubbing on the inside edge of the ejector port, I noticed it was making the grooves. I attached 4 pictures to get a second opinion. The grooves are obvious on the case, and you can see in the one picture from inside the magazine slot that there is a very rough section of metal causing the damage (at least I think it is). You can even see some metal shavings in the one picture after cycling the bolt about 5 times. Has anyone seen this before? Seems like something most smiths could fix? I don't want to start filing anything myself, that's for sure. My best guess is that one ejection cycle of a hot casing is enough to cause the grooves that I posted originally (the brass colored norma case) [url]https://picasaweb.google.com/108839979478842191491/March17201503?authuser=0&authkey=Gv1sRgCPPPh4bJhI-XXw&feat=directlink[/url] Can anyone explain how I can just insert an image as opposed to linking it? Thanks! [/QUOTE]
