Few hunting cartridges have earned the respect of the .270 Winchester like it has over decades of field use, and the Sellier and Bellot .270 Win 130gr NSR Centrefire Ammo pairs that proven cartridge with one of the most trusted projectile designs in the world. The NSR designation indicates these rounds are loaded with the Nosler Partition projectile, long considered the benchmark for reliable terminal performance on medium to large big game. Sellier and Bellot, a Czech manufacturer with over 190 years of production history, loads this ammunition to consistent, quality-controlled specifications using factory brass cases. At 130 grains (8.4g) with a muzzle velocity of 854 m/s and muzzle energy of 3,063 joules, this is a well-balanced load for a wide range of Australian hunting applications including deer, pigs, and similar-sized game.

Sellier and Bellot .270 Win 130gr NSR Centrefire Ammo - 20 Rounds Key Features

• Projectile: Nosler Partition (NSR) at 130gr (8.4g). The Partition is widely regarded as the world standard for dependable terminal performance, featuring a dual-core construction separated by Nosler's integral copper partition wall.
• Dual-Core Construction: The front lead core initiates rapid, consistent mushrooming on impact while the enclosed rear lead-alloy core is retained by the integral partition, delivering deep penetration and preventing core separation even through bone strikes.
• Weight Retention: The enclosed rear core retains more than two-thirds of the original bullet weight, ensuring deep penetration and reliable energy transfer on heavy or hard-structured game at typical hunting distances.
• Fully Tapered Copper Alloy Jacket: The jacket is engineered with a thin mouth that ruptures immediately on impact, with gradual thickening along the bullet axis. This controls the rate of expansion and produces uniform petal curl across a broad range of impact velocities.
• Muzzle Velocity: 854 m/s (tested from a 600mm barrel), delivering 3,063 joules of muzzle energy. This provides a flat trajectory and sufficient energy for ethical, clean harvests on medium to large game.
• Ballistic Coefficient: G1 BC of 0.388 and G7 BC of 0.194. These figures indicate good aerodynamic efficiency for a hunting projectile of this weight class, helping maintain velocity and energy retention at longer range.
• Sectional Density: 0.242 lb/in. A sectional density in this range is well-suited to penetration on game like deer and feral pigs, balancing penetration depth with expansion performance.
• Special Crimp Locks: Crimp locking applied during loading adds structural integrity to resist bullet seating deformation under the high chamber pressures associated with magnum-class cartridges, ensuring consistent overall cartridge length and reliable feeding.
• Casing: Factory brass. Sellier and Bellot brass is known for consistent wall thickness and reliable primer pockets, and is well-regarded as reloadable casings for handloaders.
• Cartridge Dimensions: Overall cartridge length of 82.3mm, cartridge weight of 24.5g. These dimensions are consistent with SAAMI and CIP specifications for the .270 Winchester, ensuring compatibility with standard factory-chambered rifles.
• Rounds Per Box: 20 rounds per box.

The Sellier and Bellot .270 Win 130gr NSR is a serious hunting load for licensed hunters who demand consistent terminal performance. With the Nosler Partition's hard-won reputation for stopping power, reliable expansion, and high weight retention, backed by Sellier and Bellot's precision manufacturing, this is a load you can take to the field with confidence whether you're after deer in the high country or pigs on the plains.
