The Norma African PH .416 Rigby 450gr Woodleigh RNSN is specialised dangerous game centrefire rifle ammunition engineered for maximum stopping power and controlled expansion. Loaded with an Australian-made 450-grain (29.2-gram) Woodleigh Weldcore Round Nose Soft Nose bullet, this factory ammunition generates 6,258 Joules (4,620 ft-lbs) of muzzle energy at a muzzle velocity of 655 m/s (2,150 ft/s). It is loaded into reloadable, nickel-plated brass cases designed to prevent corrosion and deliver smooth chamber feeding and rapid extraction in high-heat and humid environments.

• Woodleigh Weldcore Bonded Bullet: Features a 450gr round-nose bonded-core projectile engineered for high weight retention, deep penetration, and reliable expansion against thick hide and dense bone.
• Nickel-Plated Brass Cases: Boxer-primed, reloadable nickel-plated cases offer enhanced corrosion resistance and reduce chamber friction during cycling in extreme dust or tropical heat.
• Ballistic Profile: Delivers a sectional density of 0.371 and a G1 ballistic coefficient of 0.338, maintaining 4,956 Joules of energy at 100 metres and 3,891 Joules at 200 metres.

Who is the Norma African PH .416 Rigby 450gr Woodleigh RNSN for?

• Dangerous game hunters targeting Cape buffalo, elephant, hippo, and lion — delivers 6,258 Joules of muzzle energy through a 450-grain bonded soft-nose projectile, providing the impact energy and deep bone penetration required from .416 Rigby dangerous game ammunition at close and medium ranges.
• Professional hunters and cullers targeting Australian water buffalo and scrub bulls — provides a muzzle velocity of 2,150 ft/s in a dedicated .416 Rigby chambering, ensuring decisive stopping performance and smooth cycling via nickel-plated cases in severe field conditions.

Less suitable for: Long-range shooting beyond 200 metres where velocity decay increases, which is better served by lighter, spitzer-profile .416 cartridges; or rifles chambered in .416 Remington Magnum, .416 Ruger, or .450 Rigby, which require ammunition matched strictly to their specific chamber dimensions.
