The Norma Oryx .223 Remington 55gr (MPN 20157192) is premium bonded soft point rifle ammunition engineered for small-to-medium game hunting. Featuring a chemically bonded core and jacket, this load delivers uniform mushrooming and up to 99% weight retention upon impact. It produces a muzzle velocity of 950 m/s (3,117 fps) and 1,625 J (1,186 ft-lb) of muzzle energy from a 610 mm (24 in) test barrel, providing reliable expansion and deep penetration through bone and muscle.

• Bonded Core Technology: Uses Norma's proprietary bonding process to fuse the lead core to the copper jacket, preventing fragmentation and retaining up to 99% residual bullet weight.
• Terminal Ballistics: Delivers 1,098 J of energy at 100 m and 717 J at 200 m, with downrange velocities of 781 m/s and 631 m/s respectively.
• Reloadable Components: Loaded in high-grade brass casings fitted with non-corrosive Boxer primers.
• Broad Rifle Compatibility: The 55-grain bullet stabilises reliably across common .223 Remington and 5.56×45mm NATO barrel twist rates (including 1:12", 1:9", 1:8", and 1:7").

Who is the Norma Oryx .223 Rem 55gr for?

• Medium game hunters targeting feral goats and pigs — requires deep penetration within 150 to 200 metres, supported by this bonded soft point rifle ammunition maintaining 717 J of energy and 631 m/s velocity at 200 m with near-complete mass retention.
• Pest controllers managing foxes and small deer species — leverages a 55-grain projectile travelling at 950 m/s muzzle velocity and a 172 m Most Recommended Distance to ensure flat trajectories and rapid energy transfer inside ethical engagement zones.

Less suitable for: Hunting at distances beyond 200 m where velocity falls to 631 m/s and energy drops to 717 J, or targeting large game exceeding 50–70 kg (such as red deer or sambar deer); these applications require larger calibre rifle ammunition with higher ballistic coefficients and heavier projectile weights, such as .308 Winchester.
