The Norma Oryx .358 Norma Magnum 250gr is heavy-calibre factory ammunition engineered for hunting large, heavy-boned, and dangerous big game. Built with a bonded soft point bullet, it molecularly fuses an extra-thick copper jacket to a lead core. This construction virtually eliminates jacket-core separation, allowing the projectile to reliably retain over 90% (and up to 99%) of its original weight upon impact while expanding to more than double its original diameter for deep, straight-line penetration.

Key Features

• Bonded Core Construction: Chemical bonding between the copper jacket and lead core ensures high weight retention and prevents fragmentation against heavy bone.
• Controlled Expansion: Internal splitting zones in the front jacket initiate rapid mushrooming, while the thicker rear wall maintains structural integrity.
• High Energy Delivery: Generates 5,715 Joules of muzzle energy with a 250-grain projectile for stopping power on tough game.
• Reloadable Components: Loaded into standard Boxer-primed, reloadable brass cases.

Who is the Norma Oryx .358 Norma Magnum 250gr for?

• Hunters pursuing large Australian feral game: Relies on this .358 Norma Magnum ammunition to deliver 5,715 Joules of muzzle energy and deep, bone-breaking penetration through heavy tissue on water buffalo, scrub bulls, and large sambar deer.
• Big-game hunters targeting dangerous game and large African plains game: Employs the 250-grain bonded soft point projectile driven at 840 m/s to ensure controlled expansion and over 90% weight retention against heavy-boned animals such as moose, brown bear, and large eland.

Less suitable for: Long-range hunting beyond 300 metres, where the 0.34 G1 ballistic coefficient and blunt soft-point profile shed velocity quickly; hunters engaging targets at extended distances require dedicated low-drag, boat-tail spitzer or polymer-tipped match-hunting rifle cartridges.
