AA53, Cartridge, Caliber 5.56mm Special Ball, Long Range Mk 262 Mod 0

The Mk 262 Mod 0 quickly earned an enviable reputation in Afghanistan for excellent accuracy and superior terminal performance. Kills were made with this load out to 700 meters. According to one account, in one engagement two SF operators armed with SPRs killed 75 Taliban with 77 rounds. Upgraded to become the current MK 262 Mod 1, this load features a 77-grain Sierra MatchKing with a cannelure for reliable operation in full-automatic weapons. Ordnance Gelatin tests showed improvements in depth of initial yaw and consistency over the M855 cartridge. Work began for incorporation of Mil-SPEC primer and cartridge case, packaging and specification. Initial SPR weapons and AA53 field reports very positive. The MK 262 MOD 0 was specifically developed for use in the MK 12 SPR. A total of 27 different Off-the-Shelf cartridges were tested, leading to a down select to three, (73 gr. Berger, 87 gr. PRL, and 77gr. Sierra) Berger sold and moved facilities, causing manufacturing reliability issues, PRL shut down, leaving Sierra. The Navy, Army and USMC match teams used initial COTS load with success. The manufacture was willing to work with Government requirements. It demonstrated consistent initial yaw in soft tissue between 3-4 inches at ranges from 15' to 300 meters. This enables engagements out to 600 meters (800 possible depending on conditions). It greatly enhances the capability of the M16 or M4A1 Carbine (2 minute of angle accuracy very realistic, vs 3-5 minute of angle with M855). On 28 October 2002 The Virginia Contracting Activity, on behalf of the Defense Intelligence Agency, announced [Solicitation Number MDA908-03-Q-0008] that it intended to solicit and negotiate with Black Hills Ammunition, Inc. on a sole source basis to award a contract for MK262, Mod 0, 5.56MM 77 Grain LR Ammunition. If no affirmative written documentation, technical specifications, and pricing are received within 5 days of this synopsis challenging this intended award, to the effect that a comparable source is available or that it is more advantageous, a contract will be established with Black Hills Ammunition, Inc., P.O. Box 3090, Rapid City, SD 57709-3090.
