Ammo allotments when the Radio Compartment gun was removed

I recently came across this information concerning the  B-17 gun position ammo allotments .
Bendix chin turret - sight  & control - two 365 round ammo boxes .
Top turret - 400 rounds per gun .
Radio compartment gun - w/one - 250 round ammo box.
Ball turret - w/ two - 500 round ammo boxes.
Waist guns - w/ two -600 round ammo boxes.
Tail guns - w/two- 565 round ammo boxes.
Was this the standard ammo allotment on ALL B-17s ?
When the Radio Compartment gun was removed , was its 250 round ammo box dispersed among  the  other gun positions or was the ammo  completely eliminated to help reduce the planes weight  and increase its  range.
