Make a loadout with Minimi, 1 or more boxes, and 1 or more stangs. Fire off the box untill there are only a few bullets hanging off the gun. Reload or switch to a stang. You should see your character drop the box on the floor and more the last few bullets out of the way. You will now have 1 more stang clip then you did a moment ago containing the amount of bullets the box had left. If you do this without starting with a stang, the remaining bullets will be lost instead of being put in a stang clip. What do you think?
