Starline 300 Blackout bulk brass is precision-crafted for shooters who demand top-tier consistency, durability, and performance. Manufactured with over 30 years of experience, this brass is made from a premium 70/30 copper-zinc alloy and engineered to meet strict tolerances in diameter, length, and flash hole uniformity. Starline guarantees 100% of their brass cases meet these specifications, making them a trusted choice for reloaders looking for reliability in every round.
The 300 Blackout has become a staple cartridge for AR-15 platform shooters due to its versatility in both suppressed and unsuppressed applications. Starline’s brass supports that flexibility with consistent case wall thickness and vertical drawing methods that eliminate internal variations. Whether you’re running supersonic loads for hog hunting or subsonic rounds for tactical training, Starline’s 300 Blackout brass helps maintain reliable feeding and consistent pressure performance.
Each case is annealed between production steps to provide superior structural integrity and uniform metallurgy. This not only extends case life but also improves neck tension and reloadability. From competitive shooters and hunters to professional operators and weekend reloaders, Starline 300 Blackout brass continues to be a go-to component when accuracy and dependability matter most.
When selecting your reloading components, Starline sets the standard for quality and value. Backed by their commitment to precision manufacturing, this 300 Blackout brass delivers the confidence you need shot after shot.
