The Norma VerminXtreme .243 Winchester 76gr HP is factory centrefire rifle ammunition engineered specifically for rapid expansion and maximum terminal shock on invasive pests and predators. Loaded with a 76-grain aggressive hollow point projectile featuring a blunt nose profile, this cartridge achieves a muzzle velocity of 3,445 fps (1,050 m/s) and generates 2,002 ft-lbs (2,701 J) of muzzle energy from a standard 610 mm (24 in) test barrel. Built using reloadable Norma brass cases, it delivers reliable feeding across both bolt-action and semi-automatic rifle platforms while maintaining flat trajectories out to a Most Recommended Distance (MRD) zero of 181 metres.

Key Features

• Aggressive Hollow Point Geometry: Features a blunt-nose, fast-expanding hollow point designed to fragment violently upon impact, maximising hydraulic shock to drop pests instantly while minimising the risk of over-penetration.
• High-Velocity Varmint Performance: Produces a high muzzle velocity of 3,445 fps (1,050 m/s) with a G1 ballistic coefficient of 0.147, retaining 2,759 fps (1,284 ft-lbs) at 100 metres and 2,166 fps (792 ft-lbs) at 200 metres.
• Reliable Platform Cycling: The engineered projectile profile ensures smooth, consistent chambering and feeding in both bolt-action and semi-automatic firearms.
• Premium Reloadable Components: Built with high-grade, reloadable Norma brass cases and consistent primer and powder charges.

Who is the Norma VerminXtreme .243 Win 76gr HP for?

• Varmint hunters targeting foxes and feral cats — delivers an initial muzzle velocity of 3,445 fps from a 76-grain aggressive hollow point, providing the violent projectile expansion and hydraulic shock required for instant lethality on small predators without exiting the target.
• Pest controllers managing wild dogs and feral goats — utilizes a 76-grain hollow point projectile packaged in 20-round boxes that retains 792 ft-lbs (969 J) of kinetic energy out to 200 metres, ensuring decisive terminal performance on medium invasive pests at standard paddock engagement distances.

Less suitable for: Large game hunting, such as large deer species where deep organ penetration is required; switch to heavier 90–100 grain soft point or bonded centrefire rifle bullets to ensure controlled expansion and adequate penetration through thick hide and heavy bone.
