    Need help on a 50's Winchester model 77. I disassembeled and cleaned the rifle. It hadn't been shot in over 20 years. The cartridges seem to feed ok, but the empty cases are hanging in the chamber after they are fired and cause a jam, every time it is fired. Anyone have any ideas? Thanks.

    Couple of possibles- dirty chamber, dirty bolt face/extractor, and a chamber mouth that has been peened by dry firing.

    First, the EASY part- try a different brand of ammo. Autoloaders are notorious for being finicky on their diet. If that does not fix it-

    Next, pull the bolt, scrub GOOD around extractor, face of bolt. Clean the chamber area. You may need to put a rod down the bore, attach a slightly larger than normal brush from the breech, and pull it INTO the chamber, while turning it. I cheat and use a drill to spin the brush for about 30 seconds, with a few drops of powder solvent.

    Check fired brass for a bright line scraped into the side of the casing. Some 22s will hit the chamber mouth with the firing pin when dry fired. Done enough, this will produce a burr that drags on the brass. If you have a burr, DO NOT REMOVE IT- likely to produce reliability problems. There is a technique to IRON the burr back into place. Brownells makes a tool to do that- however, I am a cheapskate, so I use a Stanley nail set. DOES require pulling the action, bolt, etc, etc. so try ammo swap and GOOD cleaning.

    Anyone else got any thoughts? Anyone? Bueller? Anyone?
