The Norma EVOSTRIKE .308 Winchester 139gr Lead-Free Centerfire Ammunition delivers high-velocity performance, rapid fragmentation, and immediate energy transfer for non-toxic hunting. Built with a dual-core food-grade tin projectile and an aerodynamic polymer tip, this round launches at a muzzle velocity of 885 m/s (2,904 fps) and produces 3,525 J of muzzle energy from a standard 610 mm test barrel. The engineered front core features radial perforations that fragment instantly upon impact, while the solid rear core drives deep to ensure dependable tissue penetration.

Key Features

• Lead-Free Dual-Core Bullet: Constructed with a perforated tin front core for instant, explosive fragmentation and a solid tin rear core to provide reliable penetration and exit channels.
• Aerodynamic Flight Profile: Features a polymer tip and boat tail design achieving a 0.318 G1 ballistic coefficient for flat trajectories and a recommended 175 m zero distance.
• Reduced Barrel Wear: Equipped with a nickel-plated jacket that decreases bore friction and copper fouling to extend rifle barrel life.
• Reloadable Brass Cases: Loaded in premium Boxer-primed brass cases suitable for reloading.

Who is the Norma EVOSTRIKE .308 Win 139gr Ammunition for?

• Small to Medium Game Hunters — delivers rapid shock and broad terminal wound channels on feral pigs, wild dogs, and deer via a 139-grain dual-core projectile traveling at 885 m/s muzzle velocity.
• Hunters Requiring Lead-Free Compliance — provides a non-toxic tin-core design that achieves a flat-shooting 0.318 G1 ballistic coefficient with an optimal 175 m zero distance for open-country stalking.

Less suitable for: Large, heavy-boned game such as large buffalo, where deep-penetrating, bonded-core or solid monolithic copper hunting ammunition is required to prevent premature surface fragmentation.
