The Norma African PH .375 H&H Magnum loading features an Australian-made 350-grain Woodleigh Weldcore Round Nose Soft Nose (RNSN) projectile engineered for heavy and dangerous game. Operating at a muzzle velocity of 2,300 fps (700 m/s) and generating 4,112 ft-lbs (5,559 J) of muzzle energy, this heavy-for-calibre cartridge maximises sectional density and frontal momentum. The bonded lead core and heavy jacket provide controlled, uniform expansion with high weight retention, while the nickel-plated brass case ensures corrosion resistance, smooth feeding, and reliable extraction in high-heat and dirty hunting environments.

Key Features

• Heavy 350gr Woodleigh Weldcore Projectile: Features a bonded lead core and thick jacket designed for straight-line bone penetration and controlled expansion without breaking apart.
• Nickel-Plated Casing: Loaded in corrosion-resistant, nickel-plated brass cases with Boxer primers for smooth cycling and reliable ejection in harsh safari conditions.
• Optimised Close-to-Medium Ballistics: Delivers 4,940 Joules (3,670 ft-lbs) of energy at 50 metres and 4,376 Joules (3,266 ft-lbs) at 100 metres within the manufacturer's recommended impact velocity envelope.
• Standard Chamber Compatibility: Designed for .375 Holland & Holland Magnum bolt-action rifles with standard 1-in-12" or faster rifling twist rates.

Who is the Norma African PH .375 H&H 350gr Woodleigh RNSN for?

• African professional hunters and safari clients — provides heavy-for-calibre 350-grain bonded soft-nose .375 H&H dangerous game ammunition delivering 4,112 ft-lbs of muzzle energy to ensure deep tissue penetration on large bovids such as Cape buffalo.
• Australian northern safari hunters — utilises a 350-grain Woodleigh Weldcore projectile leaving the muzzle at 2,300 fps, producing the terminal momentum required to break heavy shoulder bones on feral water buffalo and scrub bulls at close-to-medium range.

Less suitable for: Open-country hunting beyond 200 metres where velocity drops below the bullet's 1,900 fps expansion threshold (lighter, higher-BC spitzer hunting ammunition is better suited), or frontal brain shots on thick-skinned game requiring non-expanding solid or full metal jacket projectiles.
