The Sellier & Bellot 8x57 JR SP (Model V331762) is factory-loaded rimmed centerfire rifle ammunition engineered specifically for classic European break-action platforms. Built with a 196-grain semi-jacketed soft point bullet featuring a tombac-plated steel jacket and an exposed lead core, it provides uniform mushrooming and deep tissue penetration on medium to large game. The rimmed case format ensures reliable mechanical extraction in single-shot rifles, double rifles, and combination guns with older J-bore barrels.

Key Features

• J-Bore Specific Bullet: Features a 0.318 in (8.08 mm) diameter soft point projectile designed strictly for vintage 8x57 JR bores.
• Controlled Terminal Performance: Semi-jacketed 196-grain (12.70 g) bullet with a lead core and Fe/CuZn 10 jacket ensures steady expansion and weight retention.
• Break-Action Mechanical Extraction: Rimmed cartridge case design ensures positive extraction in break-action combination guns, drillings, and double rifles.
• Factory Ballistics: Produces a muzzle velocity of 710 m/s (2,329 fps) and a muzzle energy of 3,201 J (2,361 ft-lb) from a standard 680 mm test barrel.
• Quality Components: Loaded in standard factory-reloadable brass cases with non-corrosive Boxer primers.

Who is the Sellier & Bellot 8x57 JR SP 196 Grain Ammo for?

• Vintage European break-action rifle owners — Requires a true 0.318 in (8.08 mm) bullet diameter to properly fit and safely engage the rifling of classic drillings, double rifles, and single-shot break-actions chambered strictly for 8x57 JR.
• Australian medium-to-large game hunters — Delivers 2,361 ft-lb of muzzle energy paired with a 196-grain soft-point projectile to generate the terminal impact and controlled tissue penetration needed for feral pigs, fallow deer, and sambar deer inside bushland distances.

Less suitable for: Modern .323 in bore rifles chambered in 8x57 JRS or rimless 8x57 JS, which require modern .323-calibre projectiles to avoid severe gas blow-by and dangerous pressure mismatches; also less suitable for open-country hunting past 200 m where bullet drop exceeds 23.0 cm and retained energy drops to 1,540 J, making higher-velocity, high-BC modern cartridges better suited.
