Olin Winchester, LLC

Olin Winchester, LLC, doing business as Winchester Ammunition, manufactures small caliber ammunition for the federal government as a prime contractor on two single-award Indefinite Delivery Contracts with a combined ceiling of $884.4 million, competing full-and-open without set-aside designations. Winchester Ammunition is a for-profit limited liability company and subsidiary of Olin Corp, a diversified chemicals and materials manufacturer based in Clayton, Missouri; Winchester Ammunition operates its manufacturing facility in Oxford, Mississippi.

Winchester's federal footprint is dominated by two large ammunition IDCs awarded to separate customers. The Program Executive Office Ammunition awarded a $145 million single-award IDC on March 28, 2022, running through March 27, 2027, covering manufacture of .38 caliber, .45 caliber, 9mm M882, and 9mm Modular Handgun System small caliber ammunition for Department of Defense pistol family and handgun system requirements. Four delivery orders issued under this vehicle total $205.2 million in obligations, including a $156.5 million FY2024 delivery order for 9mm M882 and Modular Handgun System ammunition awarded January 31, 2024, and a $22.7 million FY2025 delivery order awarded February 27, 2025. U.S. Special Operations Command awarded a second, larger single-award IDC valued at $739.4 million on July 18, 2024, extending through July 22, 2033, establishing Winchester Ammunition as the flexible procurement vehicle for ammunition products across anticipated production volumes of 2 million to 500 million rounds. Two delivery orders have been issued under the SOCOM vehicle: a $2,500 minimum initial order on July 18, 2024, and a $6.6 million Air Force delivery order on May 30, 2025, for .338 Norma Magnum linked ammunition with 272-grain match-grade projectiles. All delivery orders carry firm fixed-price or fixed-price-with-economic-price-adjustment terms and no small business set-aside.

Customer concentration is extreme. PEO Ammunition and U.S. Special Operations Command together represent 85% of recent awards and 100% of combined potential value, at $671.1 million and $739.4 million respectively. Minor award activity extends to the Department of Homeland Security Customs and Border Protection ($10 million), the Department of the Air Force ($6.6 million), and three National Park Service regional offices (collectively unspecified). Winchester Ammunition has not competed for subcontract opportunities in this data; all thirteen awards are prime positions. Activity has been episodic — one award in 2021, two in 2022, three in 2024, two in 2025, and one in 2026 — reflecting the lumpy nature of multiyear ammunition procurement. Four awards with ultimate completion dates in the next twenty-four months carry combined potential value of $350.2 million and face recompete risk, including the FY2026 PEO Ammunition delivery order due September 30, 2027, and the Air Force .338 NM ammunition order due October 28, 2026. Winchester Ammunition's capability portfolio is narrow and specialized: small caliber ammunition manufacturing across multiple calibers and ammunition configurations, categorized under NAICS 541512 (Small Arms Ammunition Manufacturing) and PSC Ammunition, Through 30mm across all thirteen awards.
