5.7 x 28 FN Brass
Our once-fired 5.7 x 28 FN Brass offers reloaders a dependable, cost-effective option for loading one of today’s most innovative small-caliber pistol cartridges. Sourced mostly from indoor ranges, this brass features mixed commercial headstamps and requires minimal cleanup, making it a practical choice for those who load for the 5.7x28mm FN platform—including the FN Five-seveN, Ruger-57, and P90/PS90 series firearms.
Each batch of brass is machine- and magnetically sorted to eliminate steel and aluminum cases. It is then visually inspected at multiple points in the process to remove any deformed or unusable cases. This ensures reloaders receive only structurally sound brass suitable for resizing and loading, even in pressure-sensitive calibers like the 5.7x28mm FN.
Orders are filled to 101% by weight and bagged securely to protect the brass during shipment. That extra 1% helps account for any potential culls or occasional nickel-plated cases. This added value supports reloaders seeking efficiency and reliability while maintaining cost control in a niche caliber.
Optional cleaning services are available for most once-fired calibers, including this one. When selected, our cleaning upgrade delivers lube-ready 5.7 x 28 FN Brass that has been tumbled and prepped—ideal for reloaders who prefer to go straight to the sizing and loading stages without additional brass prep work.
Designed for high-velocity performance and low-recoil shooting, the 5.7x28mm FN cartridge requires precision in every reload. This once-fired brass provides the case integrity, consistency, and value needed to build accurate and reliable rounds across both pistol and carbine platforms.
