Norma EcoStrike .308 Winchester is loaded with a 10.7 g lead-free copper hunting bullet for medium and large game.
Norma EcoStrike .308 Winchester is loaded with a 10.7 g lead-free copper hunting bullet for medium and large game. Its nickel-plated, tipped and boat-tail construction is designed to provide controlled expansion, deep penetration and nearly 100% retained weight. The 165 gr bullet has a manufacturer-listed muzzle velocity of 820 m/s and muzzle energy of 3599 J. Its 0.431 G1 ballistic coefficient helps it retain velocity and energy as distance increases. Suitable for use Rifles chambered in .308 Winchester Medium- and large-game hunting Wild-boar hunting Deer hunting Moose hunting Stand and stalking hunts Woodland and open-country hunting Conventional and extended hunting distances Hunting areas requiring lead-free ammunition Hunters prioritising retained weight and deep penetration Why choose Norma EcoStrike .308 Winchester?

Actual velocity, energy and point of impact depend on barrel length, the individual rifle, atmospheric conditions and the ammunition lot. Frequently asked questions What does BT-LF mean? BT refers to the boat-tail base, which reduces aerodynamic drag and supports better downrange performance. LF means lead free. The EcoStrike bullet is made from copper and has a nickel-plated surface. How does EcoStrike perform on impact? The aerodynamic tip initiates expansion when the bullet strikes. Its monolithic copper construction retains nearly all its weight according to Norma, supporting deep penetration and controlled energy transfer. Is EcoStrike completely lead free? Yes. The EcoStrike projectile is made from copper and coated with nickel. It contains no lead core and is suitable for hunting areas where lead-free bullets are required. How does EcoStrike differ from Norma Oryx? EcoStrike is a monolithic lead-free copper bullet characterised by high retained weight, deep penetration and a relatively high ballistic coefficient. Oryx is a lead-core bonded bullet whose jacket and core are joined to provide controlled expansion and good weight retention. How does the 165 gr EcoStrike differ from the 150 gr version? The 165 gr bullet is heavier and retains energy and momentum well. The 150 gr version may offer higher muzzle velocity and a slightly flatter initial trajectory. The appropriate choice depends on the game, intended distance and accuracy in the individual rifle. Is EcoStrike suitable for longer hunting distances? Its 0.431 G1 ballistic coefficient helps retain velocity and energy as distance increases. Norma states that EcoStrike can expand at both lower and higher impact velocities, but the responsible maximum distance must be determined from the rifle’s actual ballistics, remaining velocity and energy, and the shooter’s ability. Can it be used in a rifle marked 7.62×51 NATO? This cartridge is designated .308 Winchester and should only be used when permitted by the firearm manufacturer. Although .308 Winchester and 7.62×51 NATO are dimensionally similar, complete interchangeability must not be assumed. What does the 165 m MRD figure mean? MRD is Norma’s calculated most recommended zeroing distance. With the manufacturer’s 40 mm sight-height assumption, the bullet is approximately 40 mm above the line of sight at 100 m, 16 mm high at 150 m and 55 mm low at 200 m. This trajectory must be verified with the individual rifle. When is Norma EcoStrike .308 Winchester the right choice? EcoStrike is a practical choice for hunters who require a lead-free .308 Winchester bullet without giving up deep penetration or useful downrange performance. Its 165 gr weight and 0.431 G1 ballistic coefficient make it a versatile option for medium- and large-game hunting. Norma Oryx may appeal to hunters who are permitted to use lead and prefer traditional bonded construction. The lighter 150 gr EcoStrike V2 may provide greater muzzle velocity, while BondStrike is aimed more directly at users prioritising long-range ballistics. Expert recommendation A lead-free copper bullet may produce a different point of impact from a lead-core hunting load in the same rifle. Zero the rifle with EcoStrike and verify accuracy at the principal intended distances. Fire a new confirmation group whenever changing bullet type or ammunition lot. EcoStrike’s high retained weight and deep penetration do not reduce the importance of correct shot placement. Always select a direction with a safe backstop, as a monolithic bullet may retain substantial velocity and energy after complete penetration. The 165 m MRD is a calculated reference. Barrel length, scope height, atmospheric conditions and actual muzzle velocity all influence trajectory. Confirm that bullet construction, calibre and remaining energy also comply with the requirements for the intended game and hunting area. Lead-free construction with deep penetration and strong ballistics Norma EcoStrike .308 Winchester combines a 10.7 g nickel-plated copper bullet, nearly 100% retained weight and a 0.431 G1 ballistic coefficient. It is a versatile lead-free hunting load for medium and large game across varied hunting distances.
