Well, I met with Heavies today, and brought home his shiny new extractor. Thanks, Heavies!
However, it seems that a broken shell extractor just isn't gonna cut it. I guess blue Loktite is tougher than I gave it credit for!
Eh,no worries. I should take it out and shoot it as a 7.62x39 at least once anyway. Then, when I get ready to muck with it again, I'll do the old hot-lead-and-dowel trick.
