The Norma ECOSTRIKE 6.5x55 Swedish Mauser (SE) 120gr centerfire rifle ammunition (model 20166562) is engineered for ethical, lead-free hunting of light-to-medium and large game. Loaded with a 120-grain (7.8 g) monolithic copper projectile, this ammunition features an aerodynamic polymer tip, grooved waist, boat tail design, and a proprietary nickel coating that reduces barrel fouling. Delivering a muzzle velocity of 860 m/s (2,822 fps) and 2,884 Joules (2,122 ft-lbs) of muzzle energy from a standard 610 mm (24 in) test barrel, this load maintains near 100% weight retention and controlled expansion across broad impact velocities with minimal meat damage.

Key Features

• Monolithic Lead-Free Construction: Solid copper body provides near 100% weight retention with zero lead contamination in harvested meat.
• Nickel-Coated Exterior: Reduces copper fouling inside the rifle bore compared to raw monolithic projectiles.
• Engineered Expansion: Polymer tip and precision splitting grooves facilitate rapid, controlled expansion at both close and extended hunting ranges.
• Efficient Downrange Ballistics: Features a G1 ballistic coefficient of 0.390, retaining 636 m/s and 1,580 Joules of energy at 300 metres with a most recommended distance (MRD) zero of 172 metres.

Who is the Norma 6.5x55 120gr Ecostrike for?

• Medium and large game hunters — Delivers 2,884 Joules of muzzle energy and retains 1,949 Joules at 200 metres, providing the terminal penetration and flat trajectory needed for fallow deer, red deer, feral pigs, and goats when using 6.5x55 centerfire rifle ammunition.
• Non-toxic and meat-recovery hunters — Utilises a 120-grain lead-free monolithic copper projectile with a 0.390 G1 ballistic coefficient to ensure deep penetration and near 100% weight retention without lead fragmentation in game meat.

Less suitable for: Dangerous, thick-skinned heavy game such as scrub bulls and water buffalo that exceed the stopping thresholds of 120gr monolithic 6.5mm loads; large-bore centerfire ammunition (such as 9.3x62mm or .375 calibre classes) is required for these species.
