All Ultramax remanufactured ammunition goes through a 10-Step Quality Assurance System. Once fired brass is inspected for flaws and is washed to clear the primer pockets and flash holes from any debris. Ultramax sizes each piece of brass to the same SAAMI specs as new brass. Remanufactured ammunition is often loaded with mixed head stamped brass. This ammunition is non-corrosive in boxer primed, reloadable brass cases.
