The Sellier & Bellot 7.62x54R Russian Unprimed Brass Cases (part number V337752) provide reloadable cartridge brass tailored for precision handloading and vintage firearm support. Unlike standard military surplus ammunition that utilises Berdan-primed steel cases, this brass features standard Boxer primer pockets designed for standard Large Rifle primers, enabling straightforward decapping and resizing on common reloading presses. Manufactured to C.I.P. standards, each case features a nominal length of 53.72 mm, a rim diameter of 14.48 mm, and a maximum operating pressure threshold of 3,900 bar (56,565 psi). Cases are factory annealed at the neck and shoulder to ensure ductility, consistent bullet-release tension, and extended case service life across repeated firing cycles.

Key Features

• Boxer Primer Design: Configured for standard Large Rifle primers and standard decapping pins, replacing difficult-to-reload Berdan military surplus alternatives.
• Factory Thermal Annealing: Undergoes neck and shoulder annealing during manufacturing, leaving visible thermal discolouration that verifies metal ductility and resistance to work-hardening splits.
• C.I.P. Dimensional Compliance: Formed to strict European specifications with a 53.72 mm nominal case length and 14.48 mm rim diameter for consistent headspace alignment in rimmed chambers.
• Reloadable High-Pressure Rating: Engineered to withstand standard C.I.P. chamber pressures up to 3,900 bar (56,565 psi).
• Package Quantity: Supplied in convenient 20-piece packs suited for small-batch load development and ladder testing.

Who is the S&B Sellier & Bellot 7.62x54r Russian Unprimed Brass Cases 20 Pack for?

• Vintage military surplus handloaders — requires Boxer-primed 7.62x54mmR brass cases to load custom projectiles (ranging from .308 to .312 inches depending on bore groove dimensions) for historic rifles such as the Mosin-Nagant 1891/30 and SVT-40 without dealing with corrosive surplus primers.
• Target shooters competing with 7.62x54R chambered rifles — utilizes calibrated 20-piece packs of unprimed rifle brass cases rated to 3,900 bar (56,565 psi) to execute consistent powder charge ladders and uniform shoulder sizing for competitive match accuracy.

Less suitable for: Firearms chambered in rimless 7.62mm calibres; handloaders firing platforms chambered in 7.62x39mm or 7.62x51mm NATO / .308 Winchester require dedicated rimless rifle brass cases matching those specific headspace and extractor-groove dimensions.
