The Norma ECOSTRIKE™ 7mm Remington Magnum 140gr ammunition (MPN: 20171172) is engineered for medium-to-large game hunting in open country and mixed terrain. Built with a monolithic copper-nickel alloy body, this lead-free round utilizes a polymer tip and an engineered internal cavity to provide controlled expansion and nearly 100% weight retention across varying impact velocities. Designed for flat trajectories and extended energy retention, it leaves the muzzle at 950 m/s (3,117 fps) and produces 4,106 J (3,020 ft-lbs) of muzzle energy from a standard 660 mm (26 in) test barrel.

Key Features

• Lead-Free Monolithic Bullet: Features a solid copper-nickel alloy construction that eliminates lead meat contamination while reducing barrel fouling.
• Controlled Expansion: Incorporates a heat-resistant polymer tip and internal expansion cavity to maintain weight retention and deliver deep penetration at both close and extended distances.
• Aerodynamic Ballistics: Utilizes a boat-tail profile paired with a G1 ballistic coefficient of 0.443 to resist wind drift and maintain a flat trajectory out to a 192 m most recommended distance.
• Premium Reloadable Components: Loaded in high-grade, Boxer-primed non-corrosive brass cases suited for reloading.

Who is the Norma 7mm Rem Mag 140gr Ecostrike 20 Pack for?

• Red deer and sambar deer hunters in open country — utilizes a flat-shooting 0.443 G1 ballistic coefficient and a 3,117 fps muzzle velocity to deliver 2,505 J of retained energy at 300 m for clean penetration on large game.
• Feral pig and goat hunters requiring lead-free ammunition — relies on a 140-grain monolithic copper-nickel projectile designed for nearly 100% weight retention and non-fragmenting, controlled expansion without leaving lead residue in meat.

Less suitable for: Thin-skinned predators where immediate, high-velocity fragmentation is required (a dedicated fragmenting tin-core or thin-jacketed varmint bullet is better suited), or close-range brush hunting on heavy dangerous game where maximum sectional density on heavy bone calls for a heavier 150gr–170gr bonded-core lead bullet.
