The Norma 222 Rem 55gr Oryx 20 Pack is premium centerfire rifle ammunition engineered for controlled mushrooming and deep penetration on medium game and large varmints. Designed around a 55-grain (3.6 g) chemically bonded soft-point bullet, the core and jacket remain fused during impact to retain over 90% of their initial weight. Fired from a standard 610 mm test barrel, this load delivers a muzzle velocity of 930 m/s and 1,557 J of muzzle energy, making it an effective hunting cartridge within medium shooting distances.

Key Features

• Molecularly Bonded Core: Chemical bonding prevents jacket separation upon impact, ensuring high residual weight retention up to 99% for reliable penetration.
• Controlled Expansion: Features a thin forward jacket with internal splitting zones to deliver uniform, wide mushrooming at high and low impact velocities.
• Downrange Performance: Delivers a Most Recommended Distance (MRD) of 169 m, maintaining 764 m/s (1,051 J) at 100 m and 616 m/s (683 J) at 200 m.
• Match-Grade Components: Loaded in reloadable, Boxer-primed Norma brass cases engineered to tight dimensional tolerances.

Who is the Norma .222 Rem 55gr Oryx for?

• Small Game Hunters: Delivers controlled mushrooming and high weight retention at a muzzle velocity of 930 m/s, providing the deep tissue penetration necessary for targeting feral goats and pigs without the rapid surface fragmentation typical of standard thin-jacket .222 Remington ammunition.
• Varmint Hunters: Provides a flat trajectory within its 169 m Most Recommended Distance and 55 grains of terminal mass, delivering 683 J of retained energy at 200 m to cleanly dispatch wild dogs and foxes.

Less suitable for: Long-range shooting beyond 250 metres where the 0.185 G1 ballistic coefficient results in steep trajectory drop and wind drift, which is better served by higher-BC centerfire calibres such as 6.5mm or .308 Winchester, or rifles with twist rates unable to stabilise a 55-grain projectile in standard 1:14" .222 Rem barrels.
