    Red October Copper BB

    590 A1 mariner.....this is used in our military?

    Just out of the box, fired an s and b 00 buckshot, and the action freezes and will not move.
    Finally cleared it changed over to fiochi's and after a few rounds, same thing.

    Took it apart cleaned and oliled.

    Worked ok with fiochi's....then hung up on a federal 3 inch 00 buckshot.
    Tore it apart again.....appears to be a burr on the thread line of the breech hanging up the extractor. ??? How could that pass QC?

    Sent it in.
