The Norma 338 Win Mag 230gr Oryx 20 Pack delivers controlled expansion, high residual weight, and deep penetration for heavy big-game hunting. Engineered around a bonded jacketed soft point bullet, the 230-grain projectile fuses its lead core to the outer jacket to prevent core-jacket separation upon heavy impact. Producing a muzzle velocity of 840 m/s (2,756 fps) and 5,257 Joules (3,878 ft-lbs) of muzzle energy from a 660 mm (26-inch) test barrel, this factory ammunition provides substantial knockdown performance for medium-to-large game at standard hunting distances.

Key Features

• Bonded Core Construction: Chemical bonding prevents the lead core from separating from the jacket, ensuring residual weight retention between 90% and 99%.
• Controlled Mushrooming: Features a thin forward jacket with internal splitting zones to initiate rapid expansion, backed by a thicker rear jacket wall to stop over-expansion.
• Factory Ballistics: Delivers 4,292 Joules of energy at 100 metres (759 m/s) and 3,475 Joules at 200 metres (683 m/s) with a most recommended distance (MRD) zero of 168 metres.
• Reloadable Brass Cases: Loaded into standard Norma brass cases with non-corrosive boxer primers for consistent ignition and reloading capability.

Who is the Norma 338 Win Mag 230gr Oryx 20 Pack for?

• Hunters targeting mature Sambar and Red deer — provides 5,257 Joules of muzzle energy and a 230-grain bonded bullet that retains up to 99% of its mass to punch through dense bone and muscle tissue.
• Hunters pursuing heavy feral game such as scrub bulls and water buffalo — relies on a chemical-bonded .338 Winchester Magnum bullet travelling at 840 m/s to ensure deep, straight-line penetration through thick hide without premature fragmentation.
• Hunters seeking ammunition for elk, moose, and large African plains game — delivers 3,475 Joules of terminal energy at 200 metres paired with a 0.37 G1 ballistic coefficient designed for reliable terminal expansion on large-bodied game animals.

Less suitable for: Long-range shooting extending past 300 to 400 metres, where lower impact velocities can reduce mushrooming in heavy bonded bullets; high-BC polymer-tipped hunting ammunition is better suited for dedicated long-range pursuits.
