The Sellier & Bellot .30-06 Springfield NSR 180 gr (model V342772) is a factory-loaded centerfire rifle cartridge engineered for Australian big-game hunting. Utilizing the Nosler Partition dual-core projectile, this load delivers 3,596 Joules of muzzle energy at an initial muzzle velocity of 784 m/s from a 600 mm test barrel. The design splits the bullet into two distinct lead-alloy cores separated by an integral jacket partition wall, ensuring rapid frontal expansion upon impact while preserving over two-thirds of the bullet's mass to drive deep, straight penetration through heavy tissue and bone.

Key Features

• Dual-Core Partition Architecture: An internal partition wall isolates the forward lead core from the base core, providing dynamic front-end mushrooming while retaining 66%+ original projectile weight for sustained penetration.
• Progressive Tapered Jacket: Features an engineered copper-alloy jacket taper and internal crimp locks to ensure predictable expansion across varying velocities and prevent base-core dislocation.
• Precision Factory Components: Loaded in reloadable brass cases with non-corrosive Boxer primers, holding an overall cartridge length (OAL) of 83.20 mm and a total round weight of 26.6 g.
• Tested Downrange Ballistics: Maintains a 0.271 lb/in² sectional density, a G1 ballistic coefficient of 0.451, and a most recommended distance (MRD) zero of 162 metres.

Who is the S&B Sellier & Bellot 30-06 Springfield 180 Grain Nsr Nosler Partition Ammo 20 Rd for?

• Sambar and red deer hunters — Delivers 3,596 Joules of muzzle energy from a heavy 180-grain projectile that retains over 66% of its mass to punch reliably through dense shoulder bone and vitals in heavy timber out to 350 metres.
• Large feral boar and heavy scrub bull hunters — Drives 784 m/s muzzle velocity and a 0.271 lb/in² sectional density in .30-06 Springfield hunting ammunition to resist bullet fragmentation and achieve terminal straight-line penetration through thick mud shields and gristle plates.

Less suitable for: Long-range shooting beyond 350 to 400 metres where velocity drops below the 550 m/s (approx. 1,800 fps) Partition expansion threshold (where lower-drag polymer-tipped boat-tail cartridges provide flatter flight paths), or hunting thin-skinned small-to-medium game where heavy 180-grain controlled-expansion bullets cause excessive pass-through (where lighter 130–150 grain rapid-expanding soft point ammunition delivers superior shock transfer).
