The Norma Vulkan .270 Winchester 156gr ammunition (Product No. 20169412) is engineered for medium to large game hunting, delivering controlled knock-down performance. Built with a protected hollow point design, the jacket walls are folded inward over the tip of the lead core to prevent tip flattening and magazine deformation under heavy recoil. Featuring a thin front jacket combined with an external mechanical lead-lock, this 156-grain projectile achieves rapid mushrooming upon impact while retaining core-jacket integrity for deep penetration.

Key Features

• Folded-Jacket Protected Tip: Inwardly folded jacket walls shield the lead core against recoil-induced tip deformation in internal rifle magazines.
• Controlled Expansion & Retention: Thin frontal jacket allows rapid energy transfer, while a mechanical lead-lock prevents premature core separation during target entry.
• Ballistic Performance: Produces a muzzle velocity of 870 m/s (2,854 fps) and 3,822 Joules (2,822 ft-lbs) of muzzle energy from a standard 610 mm (24 in) test barrel.
• Factory Trajectory Optimization: Set with a Most Recommended Distance (MRD) of 172 metres, maintaining 2,453 Joules of energy at 200 metres.

Who is the Norma Vulkan .270 Win 156gr for?

• Sambar and Red Deer Hunters: Requires heavy frontal shock and deep penetration on large deer within 300 metres, delivered by this .270 Winchester ammunition's 156-grain bullet generating 2,854 fps of muzzle velocity and retaining 1,935 Joules of energy at 300 metres.
• Feral Pig Hunters Targeting Heavy-Bodied Game: Requires immediate terminal expansion without projectile deformation in the magazine, utilizing this .270 Winchester centerfire cartridge's folded-jacket construction and 0.34 G1 ballistic coefficient to deliver 3,080 Joules of energy at 100 metres.

Less suitable for: Open-country or extreme-range hunting extending past 300 metres where high-BC, boat-tail polymer-tipped ammunition is required to minimize drop and wind drift, or for non-standard chambers such as .270 WSM or .270 Weatherby Magnum rifles.
