The Sellier & Bellot 7 × 57 R SP 140 GRS (SKU: V331032) is centrefire rifle ammunition engineered specifically for break-action hunting platforms. Featuring a 140-grain (9.10-gram) Semi-Jacketed Soft Point projectile (Bullet #2931), this cartridge achieves a muzzle velocity of 808 m/s and a muzzle energy of 2,971 J from a standard 600 mm test barrel. Built with a reloadable brass case, non-corrosive Boxer primer, and an overall cartridge length of 73.00 mm, it is designed for controlled mushrooming, substantial wound channels, and positive mechanical extraction in single-shot and combination firearms.

Key Features

• Controlled Expansion: Features an exposed lead tip with a CuZn 10 copper-zinc alloy jacket engineered to retain projectile mass while expanding consistently upon impact.
• Rimmed Extraction Design: Formulated with a dedicated rimmed case for dependable extraction and cycling in break-action firearms.
• Downrange Terminal Ballistics: Produces 2,110 J of energy at 100 metres (681 m/s) and 1,457 J at 200 metres (566 m/s) to ensure decisive medium-range terminal performance.
• Reloadable Components: Assembled with factory-fresh reloadable brass cases and non-corrosive Boxer primers to support handloading.

Who is the S&B Sellier & Bellot 7x57r Rimmed 140 Grain Sp Ammo 20 Rd for?

• Break-action rifle hunters — Requires the dedicated 7 × 57 R rimmed case design for positive mechanical extraction in single-shot kipplauf rifles, drillings, and combination hunting guns.
• Medium-to-large game stalkers — Needs reliable terminal expansion on feral goats, wild boars, fallow deer, and red deer within 200 metres, driven by 2,971 J of muzzle energy and a 140-grain soft-point projectile traveling at 808 m/s.

Less suitable for: Long-range hunting exceeding 250 metres where downrange energy drops below 1,457 J (falling to 971 J at 300 m), which is better served by high-velocity magnum cartridges; hunting thick-skinned, dangerous game such as water buffalo and scrub bulls requiring heavy .300 Win Mag, 9.3×62mm, or .375 H&H solid or bonded loads; or bolt-action rifles chambered in rimless 7×57mm Mauser, where the cartridge rim will physically prevent proper chambering and cycling.
