The Norma 7x64 Vulkan 170gr rifle ammunition (model 20170182) is engineered for medium-to-large game hunting, providing rapid expansion and substantial energy transfer at short-to-medium distances. Loaded with an 11.0-gram (170-grain) protected hollow point bullet, the Vulkan projectile features an inverted front copper jacket tip that protects the lead core against deformation inside the magazine during recoil. Tested out of a 610 mm (24-inch) barrel, this load generates a muzzle velocity of 840 m/s and 3,881 Joules of muzzle energy, maintaining 2,521 Joules of energy at 200 metres.

• Vulkan Inverted Tip Design: Utilises a folded copper jacket tip that encases the lead core to eliminate magazine deformation and initiate rapid soft-tissue expansion on impact.
• Substantial Energy Delivery: Produces 3,881 Joules of muzzle energy ($E_0$) and retains 3,143 Joules at 100 metres for decisive knockdown power.
• Optimised Trajectory: Features a G1 ballistic coefficient of 0.353 with a Most Recommended Distance (MRD) zero of 167 metres.
• Standard Chamber Compatibility: Designed specifically for bolt-action and single-shot firearms chambered in 7x64 Brenneke.

Who is the Norma 7x64 170gr Vulkan 20 Pack for?

• Australian stalkers hunting feral pigs and red or sambar deer — delivers 3,881 Joules of muzzle energy and 2,521 Joules at 200 metres through a fast-expanding 170 grains bullet designed to drop medium and large feral game quickly in close-to-medium timber.
• European driven hunt participants targeting wild boar and red deer — utilizes an 11.0-gram (170-grain) projectile exiting the muzzle at 840 m/s with an inverted copper jacket to prevent magazine tip damage and deliver immediate expansion on running game within a 167 m recommended zero distance.

Less suitable for: Extended long-range shooting beyond 300 m where the 0.353 G1 ballistic coefficient results in a 39.6 cm drop from a 150 m zero, making streamlined, high-BC polymer-tipped bullets a better choice; or ultra-dense thick-skinned game requiring deep straight-line bone penetration over violent soft-tissue expansion, where bonded-core or monolithic solid bullets are better suited.
