Load: Put 2 shells in the mag, then hit the button underneath that makes it spit a round out of the mag, then cycle the action, than top off the mag.
Unload: Cycle the action to remove the one in the chamber, then reach into the magwell and push the catch that releases the shell into your hand, repeat.
If I am just gonna put it in the truck or the scabbard, I just take the shell out of the chamber. This is one thing that I love about my Benelli, that you dont have to cycle all of the shells thru the chamber to unload it.
