The Norma 7mm Remington Magnum 170gr Vulkan centrefire ammunition is engineered for medium to large game hunting and driven hunts where rapid expansion and high immediate stopping power are critical. Featuring a 170 gr (11.0 g) protected soft point projectile, the Vulkan bullet is designed with a folded jacket nose that protects the lead core against deformation inside the magazine during recoil. Built with a thin forward jacket section, it delivers rapid mushrooming and high energy transfer upon impact, while an external jacket lock ring anchors the core to control expansion and maintain penetration.

Key Features

• Inverted Jacket Tip: Features front jacket walls folded inwards over the lead core to prevent recoil-induced tip flattening in the magazine.
• Rapid Energy Transfer: Thin forward jacket construction initiates instant expansion and shock delivery upon target contact.
• External Lock Ring: Anchors the lead core within the jacket to retain structural weight and facilitate controlled downrange penetration.
• Standard Chamber Compatibility: Designed specifically for hunting rifles chambered in 7mm Remington Magnum.

Who is the Norma 7mm Rem Mag 170gr Vulkan 20 Pack for?

• Medium to large game hunters — Delivers heavy impact through a 170 gr bullet launched at 2,953 ft/s (900 m/s), providing 4,455 J of muzzle energy and consistent, rapid mushrooming across standard hunting distances up to 200–300 metres on species such as red deer, fallow deer, sambar, and wild boar.
• Driven game hunters — Utilises a 0.353 (G1) ballistic coefficient semi-jacketed projectile with a thin forward jacket designed to initiate immediate kinetic energy transfer and stopping power at close-to-medium ranges.

Less suitable for: Extended long-range hunting beyond 300 to 400 metres where high-BC polymer-tipped boat-tail projectiles are required for wind resistance and flat trajectory, or for deep bone-breaking penetration through heavy shoulders on dangerous game where heavily bonded hunting bullets are preferred over rapid explosive expansion.
