New 40 rounds of 647 grain 50 BMG ball ammo from Thunder Ammo. We refer to this ammunition around our shop as "Match Ball" because the same quality & care goes into each round that we put into our competition ammo. These 647 gr. projectiles are inspected & weight sorted by hand, we use new Winchester brass & Hodgdon powder weighing each powder charge by hand, one at a time. All of our ammo goes through several inspection processes both during production and before shipping to ensure you with a product that will deliver the performance & quality you expect. Comes in nice reusable plastic ammo boxes. Thanks, Randy
