The Norma 308 Win 150gr Ecostrike ammunition is a lead-free hunting cartridge engineered for deep penetration, maximum weight retention, and reliable terminal performance on medium-to-large game. Loaded with a 150-grain (9.7-gram) nickel-coated monolithic copper projectile, it features a polymer expansion tip and a boat-tail base that achieve a ballistic coefficient of 0.376 (G1). Fired from a standard 610 mm test barrel, it produces a muzzle velocity of 860 m/s (2,822 fps) and 3,587 Joules (2,651 ft-lbs) of muzzle energy. The nickel plating minimizes copper fouling in the barrel, while the engineered internal expansion cavity ensures controlled petal expansion with up to 99–100% weight retention.

Key Features

• Lead-Free Copper Construction: Monolithic solid copper bullet eliminates lead fragmentation, reducing meat contamination while maintaining up to 99–100% weight retention.
• Nickel Plating: Reduces copper fouling inside the rifle bore to extend barrel life and maintain consistent accuracy across shot strings.
• Aerodynamic Expansion Tip: Polymer tip and boat-tail base enhance aerodynamic efficiency and initiate reliable expansion upon impact.
• Optimised Trajectory: Retains 701 m/s (2,344 fps) and 2,383 Joules of energy at 200 metres, with a Most Effective Range Distance (MRD) of 171 metres.
• Premium Reloadable Components: Built with high-grade reloadable brass cases and non-corrosive Boxer primers.

Who is the Norma .308 Winchester 150gr ECOSTRIKE for?

• Medium-to-large game hunters — Delivers 3,587 Joules of muzzle energy and 1,919 Joules of residual energy at 300 metres from a 150-grain projectile, providing the stopping power and near-100% weight retention required for feral pigs, fallow deer, red deer, sambar deer, and goats.
• Hunters in lead-restricted areas — Utilises a 100% lead-free, nickel-plated monolithic copper bullet with a 0.376 (G1) ballistic coefficient that complies with non-toxic hunting mandates without sacrificing downrange velocity.

Less suitable for: Shots beyond 350 to 400 metres where velocity drops below the minimum terminal threshold required for monolithic copper expansion (where high-BC bonded lead-core hunting ammunition is better suited), or for hunting dangerous heavy game such as water buffalo, which requires larger magnum calibres.
