Most all if not all ammo comes in flats. I know we have a dealer here that will give u a better price if u by a flat of any of hes ammo. The ammount of shells or cartridges in a flat depends on type or maker.

Your local gun shop can and will order anything your want in any quantity you want. Be prepared to pay up front.
