The Norma .300 Winchester Magnum 180gr Vulkan ammunition (MPN: 20175752) is engineered for short-to-medium range large game hunting where immediate energy transfer and rapid expansion are required. Loaded with a 180-grain (11.7 g) Vulkan protected soft-point bullet, this cartridge leaves a 660 mm test barrel at a muzzle velocity of 920 m/s (3,018 fps) and generates 4,951 J of muzzle energy. The bullet features a specialised folded copper jacket over the tip of the lead core, preventing deformation from heavy recoil inside the magazine while ensuring rapid mushrooming upon impact to anchor game on the spot.

Key Features

• Rapid Expansion: Built with a thin forward jacket designed to initiate immediate, violent expansion and dump terminal energy rapidly into target tissue.
• Protected Soft-Point Tip: Features a copper jacket folded over the nose of the lead core to eliminate bullet tip damage during magazine cycling and recoil.
• Centrefire Ballistic Profile: Generates 3,924 J of energy at 100 m and 3,075 J at 200 m, with a Most Recommended Distance (MRD) zero of 180 m.
• Chamber Compatibility: Specifically loaded for rifles chambered in .300 Winchester Magnum.

Who is the Norma .300 Win Mag 180gr Vulkan 20 Pack for?

• Sambar deer hunters operating within 200 metres — Requires 3,075 J of energy at 200 m delivered via an 180-grain rapid-expanding projectile, making this .300 Win Mag hunting ammunition effective at dropping heavy deer in close bush terrain.
• Wild boar and feral pig hunters requiring immediate stopping power — Needs the 920 m/s muzzle velocity and thin forward jacket design of this .300 Win Mag hunting ammunition to dump hydrostatic energy instantly on running or driven game.

Less suitable for: Shooting beyond 300 metres, where its 0.315 G1 ballistic coefficient causes significant velocity loss, making a high-BC bonded or polymer-tipped projectile better suited; or for heavy-boned game exceeding 150 kg requiring deep penetration through thick shoulder bone, where a bonded core or monolithic copper bullet is more appropriate.
