The Norma ECOSTRIKE .270 Winchester Short Magnum (.270 WSM) 130gr Rifle Ammunition (MPN 20169582) is a factory-loaded, lead-free hunting cartridge engineered for deep penetration and controlled terminal expansion on medium to large game. Featuring a 130-grain (8.4g) monolithic copper projectile with an aerodynamic polymer tip, this cartridge delivers a 0.360 G1 ballistic coefficient for a flat trajectory across open country. The projectile is finished with nickel plating to minimise bore fouling, while an engineered expansion cavity with four internal relief cuts initiates consistent mushrooming and near-100% weight retention upon impact. Each factory box contains 20 rounds loaded in premium reloadable Norma brass cases with boxer primers.

Key Features

• Monolithic Lead-Free Construction: Solid copper-alloy projectile eliminates lead fragmentation while maintaining near-100% weight retention through heavy bone and dense muscle tissue.
• Nickel-Coated Exterior: Plated projectile surface reduces copper fouling in the rifle bore, extending barrel life between cleanings.
• Aerodynamic Profile: Polymer tip and boat-tail base produce a 0.360 G1 ballistic coefficient for reduced aerodynamic drag and enhanced downrange wind resistance.
• Controlled Terminal Expansion: Internal relief cuts behind the tip allow reliable mushrooming across close-range high-velocity hits and standard hunting distances out to 300–400 metres.
• Reloadable Norma Brass: Boxer-primed, high-grade brass casings built to exact tolerances for consistent chambering and repeated handloading.

Who is the Norma ECOSTRIKE .270 WSM 130gr Ammunition for?

• Medium-to-large game hunters — requires the high-velocity, flat trajectory of a .270 WSM calibre cartridge pushing a 130-grain monolithic bullet with a 0.360 G1 ballistic coefficient to deliver deep penetration and reliable expansion on species such as Red deer, Sambar, Fallow deer, and feral pigs out to 300–400 metres.
• Hunters in regulated or conservation hunting zones — needs non-toxic rifle ammunition that complies with lead-free mandates on protected properties and state forests while maintaining full terminal performance via a 130-grain solid copper projectile.

Less suitable for: Long-range hunting past 500+ metres where impact velocity drops below the threshold required for monolithic copper expansion, dangerous large game like Water Buffalo requiring heavy-calibre magnums (.338 or .375 calibres), or standard .270 Winchester and .270 Weatherby Magnum actions requiring standard-length or belted magnum cartridges.
