BROKEN SHELL EXTRACTOR
This tool will help you clear a broken shell case that is lodged in your barrel.
To use, remove the entire shell extractor unit (3 pieces) from the base of the
tool handle. Be sure that all 3 pieces are still attached and that the extractor
pin is not tight so it does not cause the end to flare. Lock the action of your
rifle in the open position. Next, drop the shell extractor tool into the
chamber (pin side towards the muzzle) and close the action. Cycle the
action to remove the broken shell extractor with the broken shell attached.
Repeat if necessary. Unscrew the inner pin to remove the broken shell
casing from the extractor tool.
