[QUOTE="Kevin Cram, post: 201334, member: 2215"] I assume this was a factory Remington barrel? The "gummy stuff" is Remingtons idea of tolerance filler. Their barrel threads are cut so sloppy they pack the threads with some sort of super high strength epoxy to tighten up the fit and then bond the barrel to the action. I have to apply some heat to the action with a propane torch just enough to melt the epoxy before I can remove a factory Remington barrel. You know it's melting when you see smoke come out of the front scope base screw hole. If you are attaching the same barrel back on it's best to make sure you have all the eoxy cleaned off the barrel threads. A brass brush will work fine, but the action threads will need cleaned out too. Best advise would be to get a 1 1/16 -16 tap to clean that out. The tap won't oversize the thread, just clean out all the gunk and may take out some of the taper. A little anti-sieze won't hurt either but use it sparingly, a little goes a long way. [/QUOTE]
