The Norma ODIN .300 Winchester Magnum 11.7g / 180gr factory ammunition delivers high-retention terminal performance designed for medium-to-large game. Loaded with a 100% monolithic copper, polymer-tipped boat tail projectile, this lead-free round generates a muzzle velocity of 905 m/s (2,969 fps) and 4,793 J (3,524 ft-lbs) of muzzle energy from a standard 660 mm (26 in) test barrel. Built to CIP and SAAMI dimensions, it provides straight-shooting external ballistics paired with an active expansion envelope rated from 0 m to beyond 400 m.

Key Features

• Solid Monolithic Construction: Machined from 100% solid copper to ensure near 100% weight retention, high structural integrity, and lead-free compliance without fragmenting in dense tissue.
• Polymer Tip & Cavity: Features a streamlined polymer tip seated over an engineered expansion cavity to initiate rapid, uniform petal deformation at impact velocities down to downrange hunting thresholds.
• NAFT Friction-Reducing Coating: Treated with Norma's proprietary NAFT coating to reduce bore friction, limit copper fouling, and prolong rifle barrel service life during sustained range and field use.
• High Retained Downrange Energy: Produces 4,090 J (3,048 ft-lbs) of energy at 100 m, 3,472 J (2,626 ft-lbs) at 200 m, and 2,931 J (2,252 ft-lbs) at 300 m to ensure reliable vital-zone impact delivery.

Who is the Norma Odin .300 Win Mag 180gr for?

• Open-terrain red deer hunters — requires the flat trajectory and high wind resistance provided by this .300 Win Mag hunting ammunition's 0.462 G1 ballistic coefficient and 905 m/s initial muzzle velocity.
• Sambar deer stalkers — relies on the 180 grains (11.7 grams) monolithic copper bullet to deliver deep straight-line penetration and near 100% weight retention through heavy bone and muscle tissue.
• Wild boar hunters — demands substantial terminal authority at practical shooting distances, utilising this load's 4,090 J of retained energy at 100 m for decisive stopping power on heavily shielded boars.

Less suitable for: Extreme long-range shooting past 500 to 600 metres where higher-BC bonded polymer-tipped bullets (exceeding 0.600 G1 BC) are required to maintain expansion velocity, or small game and varmint applications where lighter, rapid-expanding sub-150-grain rounds are better suited to prevent over-penetration.
