Refactor of loose ammo boxe

The idea is to have only one empty box for loose ammo.
when you would
because as far as i understand the only difference is overlay and description of the boxes.
so that would reduce the number of code requested.
i don’t know how to code it so i post it here.

you mean one box for all ammo types? how would you get the ammo you want, and why not just use the original ammo box?
