The Sellier & Bellot 6.5x57R Rimmed Unprimed Brass Cases provide virgin, reloadable cartridge cases specifically manufactured for handloading European break-action rifle ammunition. Produced in the Czech Republic to strict C.I.P. dimensional standards, these components are engineered for single-shot break-actions (Kipplauf), combination guns (Bockbüchsflinte), and drillings. Each case features standard Boxer primer pockets with a single flash hole, allowing handloaders to deprime and resize brass using standard reloading dies without specialised tooling.
