The Norma Whitetail .243 Winchester 100gr Soft Point ammunition is engineered for reliable terminal performance on medium-sized game and pest management. Loaded with a traditional flat-base soft point (SP) projectile weighing 100 grains (6.5 grams), this factory ammunition delivers consistent expansion and energy transfer across short- to medium-range hunting scenarios. Each round features premium boxer-primed, reloadable brass cases built to standard SAAMI and CIP chamber specifications, offering smooth feeding and reliable cycling in bolt-action and compatible hunting rifles.

Key Features

• Controlled Terminal Expansion: Features an exposed lead tip and tailored jacket designed to mushroom rapidly upon impact, transferring 2,633 J of muzzle energy directly into vital organs.
• Optimised Ballistic Profile: Engineered with a G1 ballistic coefficient of 0.257, providing flat trajectories for mid-range hunting with a factory-recommended Most Recommended Distance (MRD) zero of 172 metres.
• Premium Reloadable Cases: Built with high-grade virgin brass cases and non-corrosive boxer primers for dimensional consistency and repeated handloading.
• Predictable Downrange Performance: Delivers a muzzle velocity of 900 m/s (2,953 fps) from a standard 610 mm test barrel, maintaining 1,446 J of energy at 200 metres.

Who is the Norma Whitetail .243 Win 100gr SP for?

• Medium game hunters — requires a 100-grain soft-point projectile that leaves the muzzle at 900 m/s to achieve rapid hydrostatic shock and controlled mushrooming on fallow deer, chital, feral goats, and pigs within 200 metres.
• Pest and predator controllers — utilizes 243 Winchester hunting ammunition maintaining 1,972 J of kinetic energy at 100 metres with a 0.257 G1 ballistic coefficient for flat-shooting pest eradication out to standard field zero ranges.

Less suitable for: Long-range shooting beyond 300 metres where velocity drops to 566 m/s and energy falls to 1,041 J (where higher-BC polymer-tipped or boat-tail cartridges are better suited), or hunting large, heavy-boned game such as Sambar deer, scrub bulls, and water buffalo, which require heavier bonded projectiles or larger calibres for adequate penetration.
