The Norma Oryx 7.5x55mm Swiss 180 gr Bonded Soft Point is factory-loaded hunting ammunition designed for medium to large game. Featuring Norma's chemically bonded bullet design, the copper jacket and lead core remain fused upon impact to prevent fragmentation and maintain high residual weight. Firing a 180-grain projectile at a muzzle velocity of 820 m/s and delivering 3,934 Joules of muzzle energy from a standard 610 mm test barrel, this load provides controlled expansion, deep penetration, and reliable terminal performance on game such as deer and wild boar.

Key Features

• Bonded Core Construction: Metallurgically fuses the lead core to the copper jacket to eliminate separation, ensuring weight retention up to 90–99% under standard hunting conditions.
• Terminal Ballistics: Generates rapid, uniform mushrooming upon soft-tissue impact to create a wide, ethical wound channel without premature breakup.
• Premium Reloadable Cases: Loaded in Boxer-primed, high-grade reloadable brass cases suited for multiple handloading cycles.
• Trajectory & Energy: Features a G1 ballistic coefficient of 0.354 with a factory Most Recommended Distance (MRD) of 163 metres.

Who is the Norma Oryx 7.5x55 Swiss 180gr for?

• Hunters using Swiss surplus and sporting rifles — Fires directly from 7.5x55mm Swiss platforms like the Schmidt-Rubin and K31, pushing a 180-grain bonded soft point at 820 m/s for harvesting wild boar and deer.
• Medium-to-large game hunters within standard ethical distances — Retains 2,009 Joules of kinetic energy at 300 metres with this 7.5x55mm Swiss hunting ammunition, delivering the hydrostatic shock and deep penetration required inside 0 to 300 metres.

Less suitable for: Dedicated long-range shooting beyond 300 to 400 metres where a G1 ballistic coefficient of 0.354 causes increased wind drift and drop; dedicated high-BC, polymer-tipped boat-tail cartridges are better suited for extended distances. It is also incompatible with firearms chambered in .308 Winchester or 7.5x54 French.
