The Sellier & Bellot .308 Winchester 180 Grain NSR rifle ammunition is factory-loaded with the dual-core Nosler Partition spitzer bullet for medium-to-large big game hunting. Built for heavy bone breaking and high weight retention, the partitioned jacket features a solid copper-alloy cross-wall that locks the rear lead core in place while allowing the front lead core to expand uniformly. This design ensures between 65% and 70%+ weight retention across close and medium engagements. Each factory round is assembled with reloadable Boxer-primed brass cases to standard CIP specifications.

Key Features

• Partitioned Bullet Design: Employs a dual-core projectile with an integral copper partition, driving deep straight-line penetration through heavy muscle and bone while preventing core separation.
• Controlled Terminal Expansion: Tapered gilding-metal jacket initiates reliable mushrooming upon impact across varying impact velocities.
• Consistent Factory Ballistics: Produces a muzzle velocity of 745 m/s and 3,247 Joules of muzzle energy from a standard 600 mm test barrel.
• Reloadable Brass Cases: Assembled with quality Boxer-primed 5.3 Large Rifle primers and standard brass casings for consistent chambering and field reloading.

Who is the S&B Sellier & Bellot 308 Win 180 Grain Nsr Nosler Partition Ammo 20 Rd for?

• Sambar and red deer hunters operating at close to medium ranges — relies on 3,247 Joules of muzzle energy and a 180-grain controlled-expansion projectile to deliver deep penetration through thick shoulders within 0 to 250 metres using this .308 Win hunting ammunition.
• Hunters targeting large feral boars, scrub bulls, and feral camels — requires the 71.10 mm overall length .308 Win cartridge pushing a heavy 180-grain partitioned bullet at a muzzle velocity of 745 m/s to reliably smash heavy bone without fragmenting prematurely.

Less suitable for: Long-range shooting beyond 300 to 400 metres, where higher-BC boat-tail or polymer-tipped match projectiles provide flatter trajectories, or for light game such as fallow deer, goats, and foxes, where standard 130 to 150 grain soft-point ammunition delivers faster energy dump without over-penetration risks.
