    870 LW has developed shell feeding malfunction. Slowly cycling the action will chamber the shell, cylcing the action fast results in the shell not high enough to enter the chamber, and the extractor puts a groove in the rim. Removing the extractor it functions normally. Attached photo shows the jam, After polishing a few burrs off with no improvement I am running out of ideas what could be the cause other than a bent carrier or worn carrier dog, this gun has not been shot much, any suggestions?

    Thanks

    CARRIER DOG SPRING MAY BE WEAK. TRY ONE FROM A 1187 12 GA OR 870 POLICE ETC AS THEY HAVE TO LIFT HEAVIER SHELLS.

    I had one acting very similar to yours.

    I put a new carrier/ lifter assembly in and the problem went away

    Thanks for the input, I considered a new lifter assy., but not the carrier dog spring. This is a 20 year old 870 that has been used for hunting occasionally, then decided to use it for a pump gun 5 stand league for fun.

    Is that a re-load? The shell is not rounded at the crimp. and this will affect shell feeding. Does it work OK with new shells?
