OLIN WINCHESTER LLC

Olin Winchester LLC specializes in the manufacturing of small arms ammunition for federal law enforcement and public safety agencies, with deep expertise in lead-free, reduced-hazard, and mission-specific training rounds. The company produces a range of calibers—including 9mm, 12-gauge shotgun shells, and other small arms cartridges—tailored for agency-specific operational needs such as officer training, wildlife management, and correctional facility security. Their technical capabilities encompass precision propellant formulation, environmentally compliant munitions design, and rigorous quality control aligned with federal ballistic and safety standards. A key differentiator is their consistent delivery of specialized training ammunition that minimizes environmental impact while maintaining performance integrity, making them a trusted partner for agencies prioritizing sustainability and safety. The contractor maintains strong, recurring relationships with the Department of the Interior, Department of Homeland Security, and Department of Justice, supplying ammunition for U.S. Fish and Wildlife Service law enforcement, Customs and Border Protection training programs, and Federal Correctional Institution restocking. These engagements reflect a pattern of long-term, mission-critical support for field operations requiring reliable, high-volume ammunition procurement under tight operational timelines. Olin Winchester’s primary industry focus is in small arms ammunition manufacturing (NAICS 332992), with supplementary experience in broader ammunition and explosives production (NAICS 332993 and 325920). The company is positioned as a niche supplier for federal law enforcement and natural resource protection agencies seeking specialized, non-standard munitions not typically offered by commercial defense contractors. Based in East Alton, Illinois, Olin Winchester LLC operates as a small business under the 2L entity structure. The company holds no federal certifications but leverages its manufacturing precision and agency-specific responsiveness to maintain a consistent presence in the federal law enforcement supply chain.
