The Sellier & Bellot 9.3×74R SP Ammunition is a heavy centrefire hunting cartridge engineered for break-action rifles, including double rifles, drillings, and kipplauf platforms. Loaded with an 18.5-gram (286-grain) semi-jacketed soft point bullet, this ammunition delivers controlled mushrooming and deep penetration through dense bone and heavy muscle. Operating at a muzzle velocity of 705 m/s and producing 4,597 Joules of muzzle energy from a standard 650 mm test barrel, it provides substantial stopping power for medium- to close-range heavy-game hunting.

• Controlled Expansion: Features a CuZn brass jacket surrounding an exposed lead core to deliver progressive expansion and rapid hydrostatic shock upon impact.
• Terminal Energy Transfer: Retains 3,515 Joules of energy at 100 metres and 2,640 Joules at 200 metres, maintaining terminal lethality on thick-skinned and large-bodied animals.
• Break-Action Reliability: Sized to an overall cartridge length of 94.5 mm with a rimmed extraction design tailored specifically for hinged break-action rifle mechanisms.
• Weight Retention: Built with a heavy jacket construction that prevents core separation, ensuring reliable wound channels through heavy game tissue.

Who is the Sellier & Bellot 9.3x74R 285 Grain SP Ammo for?

• Hunters targeting heavy feral water buffalo in the Northern Territory — Requires massive kinetic energy transfer and reliable bone-breaking penetration, provided by this 9.3x74R ammunition producing 4,597 Joules of muzzle energy and an 18.5-gram (286-grain) soft point projectile.
• Hunters targeting large scrub bulls and feral boars — Demands deep penetration through dense shoulder tissue at moderate ranges, achieved by this 9.3x74R soft point round driving a 286-grain bullet at a 705 m/s muzzle velocity.
• Hunters targeting large deer species such as Sambar — Delivers controlled expansion and 3,515 Joules of retained energy at 100 metres from a 9.3x74R centrefire cartridge, ensuring clean terminal performance inside typical forested game distances.

Less suitable for: Long-range engagements beyond 150 to 200 metres, where the 0.308 G1 ballistic coefficient results in steep bullet drop (-21.0 cm at 200 metres with a 100-metre zero, and -76.7 cm at 300 metres); higher-velocity, flatter-shooting calibres with aerodynamic polymer-tipped bullets are better suited for open-country hunting past these distances. It is also completely unsuitable for rimless bolt-action rifles, which require dedicated rimless cartridges such as 9.3×62mm.
