The Norma 270 Wsm 156gr Vulkan 20 Pack is a factory-loaded hunting cartridge engineered for rifles chambered specifically in .270 Winchester Short Magnum (.270 WSM). Manufactured in Sweden by Norma Precision, this load features a 156-grain (10.1 g) Vulkan soft point projectile designed for short- to medium-range engagements on medium-to-large game. The bullet uses an inverted, folded-jacket front design that shields the lead core from recoil deformation inside the magazine, while a thin forward jacket and external lead lock ensure rapid mushrooming, strong shock effect, and controlled penetration on impact.

Key Features

• Inverted Jacket Tip: The forward jacket wall folds inwards over the lead core, preventing nose deformation caused by heavy magazine recoil.
• Rapid Knockdown Dynamics: Built with a thin forward jacket for fast expansion and energy dump, backed by a thicker base jacket and external lead lock to prevent core separation.
• High-Velocity Magnum Performance: Achieves a muzzle velocity of 910 m/s and delivers 4,182 J of muzzle energy when tested in a 610 mm barrel.
• Factory Packaging: Supplied in standard boxes of 20 rounds for field and range use.

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

• Deer hunters targeting red, sambar, and fallow deer — relies on the 4,182 J muzzle energy and heavy 156 gr Vulkan projectile to deliver rapid energy dump and controlled penetration inside standard hunting ranges.
• Feral pig and feral goat hunters — leverages the 910 m/s muzzle velocity and quick-expanding soft point profile of this .270 WSM hunting cartridge to produce decisive knockdown on heavy-bodied pest species.

Less suitable for: Long-range hunting beyond 300 m where the 0.34 G1 ballistic coefficient increases drop and wind drift (a dedicated high-BC polymer-tipped or bonded long-range cartridge fits this better), or standard .270 Winchester rifles due to incompatible chamber dimensions.
