The Sellier & Bellot 6.5×57R SP (Semi-Jacketed Soft Point) 131 gr ammunition delivers reliable feeding, positive rimmed extraction, and controlled expansion for European-pattern sporting firearms. Engineered specifically for break-action platforms, this factory load couples an 8.50 g exposed-lead-core projectile with a CuZn 10 brass jacket. Fired from a standard 600 mm test barrel, it develops a muzzle velocity of 775 m/s (2,543 fps) and 2,553 J (1,880 ft-lbs) of muzzle energy, producing rapid initial mushrooming while retaining bullet mass for deep penetration on medium game.

Key Features

• Break-Action Reliability: Features a rimmed ("R") brass case engineered for positive mechanical extraction in single-shot break-action rifles, drillings, combination guns, and double rifles.
• Controlled Terminal Expansion: Utilises bullet #2923 with an exposed lead core and CuZn 10 jacket that initiates consistent mushrooming on impact while limiting core separation.
• Downrange Energy Retention: Carries a G1 ballistic coefficient of 0.389 (G7: 0.195) and a sectional density of 0.269 lb/in², retaining 1,688 J of energy at 200 m and 1,352 J at 300 m.
• Reloadable Quality Components: Loaded in factory-fresh reloadable brass cases with non-corrosive standard Boxer primers, maintaining an overall cartridge length (OAL) of 77.00 mm.

Who is the S&B Sellier & Bellot 6.5x57r 131 Grain Sp Ammo 20 Rd for?

• Hunters using break-action rifles and combination guns — Requires a true rimmed 6.5×57mmR case to ensure positive manual or mechanical extraction in break-action single-shot rifles, drillings, and combination guns, which cannot reliably cycle or extract rimless alternatives.
• Medium-game hunters targeting deer, pigs, and goats — Delivers 2,553 J of muzzle energy and retains 1,688 J at 200 metres using a 131 gr soft-point projectile engineered for rapid hydrostatic shock and deep terminal penetration on roe deer, fallow deer, chamois, and wild boar.

Less suitable for: Target shooting past 300 to 400 metres due to bullet drop (-55.0 cm at 300 m on a 100 m zero) where high-BC match projectiles are required, hunting heavy or dangerous game such as large red stag or water buffalo where heavier .30-calibre bonded or monolithic cartridges are necessary, or firearms chambered in rimless 6.5×57mm Mauser, 6.5×55mm SE, or 6.5 Creedmoor.
