The Norma .300 Win Mag 165gr ECOSTRIKE ammunition delivers high-velocity, non-lead terminal performance engineered for medium to large game hunting. Featuring a monolithic copper projectile with a polymer tip and boat-tail base, this round achieves a muzzle velocity of 3,248 fps (990 m/s) and a muzzle energy of 3,506 ft-lbs (4,754 Joules). The nickel-coated construction reduces barrel fouling while ensuring nearly 100% weight retention and controlled expansion across a wide velocity spectrum.

Key Features

• Lead-Free Copper Construction: Built from pure monolithic copper with a nickel coating, yielding high weight retention and deep penetration without lead fragmentation.
• Aerodynamic Ballistics: Utilises a polymer tip and boat tail to achieve a G1 ballistic coefficient of .431, maintaining a flat trajectory and downrange energy.
• Internal Expansion Cavity: Engineered to initiate uniform expansion from high magnum impact speeds down to medium-low velocities.
• Reloadable Components: Loaded in premium reloadable brass casings with non-corrosive Boxer primers.

Who is the Norma .300 Win Mag 165gr ECOSTRIKE 20 Pack for?

• Sambar deer hunters in Victoria — Requires deep penetration and near-100% weight retention through heavy bone, driven by a 165 grains monolithic projectile travelling at 3,248 fps in this .300 Win Mag hunting ammunition.
• Red and fallow deer stalkers — Benefits from the flat trajectory and wind resistance provided by a G1 .431 ballistic coefficient for medium-to-long-range field shooting.
• Hunters operating in lead-restricted zones — Requires completely lead-free .300 Win Mag hunting ammunition engineered with a monolithic solid copper design that complies with non-lead environmental requirements.

Less suitable for: Extreme-range hunting beyond 400 to 500 metres where impact velocities drop below the expansion threshold of monolithic solids (consider specialized high-BC long-range soft-point hunting loads), or rifles chambered in non-.300 Win Mag cartridges such as .300 WSM, .300 PRC, or .300 Weatherby Magnum.
