The Norma 243 Win 100gr Oryx 20 Pack is premium centerfire hunting ammunition engineered for deep penetration and high weight retention on medium game. Loaded with a 100-grain chemically bonded jacketed soft point projectile, the core and jacket are fused to prevent jacket separation upon high-velocity impact. Leaving a standard 610 mm test barrel at a muzzle velocity of 910 m/s (2,986 fps) with 2,691 Joules of muzzle energy, this round produces controlled mushrooming via internal jacket splitting zones, routinely retaining over 90% of its initial weight for straight-line penetration through bone and muscle.

Key Features

• Chemically Bonded Core: Fuses the lead core to the outer jacket to virtually eliminate core-jacket separation and maximise structural integrity upon impact.
• High Weight Retention: Engineered with a thin forward jacket and a reinforced rear jacket to deliver controlled expansion with retained weight commonly exceeding 90% (up to 99%).
• Terminal Downrange Energy: Carries 2,039 Joules of energy at 100 metres and 1,516 Joules at 200 metres, with a Most Recommended Distance (MRD) zero of 174 metres.
• Reloadable Components: Built with premium Norma brass casings and non-corrosive Boxer primers.
• Barrel Twist Optimisation: Designed to stabilise reliably in standard .243 Winchester factory barrel twist rates of 1:10" or 1:9.25".

Who is the Norma 243 Win 100gr Oryx 20 Pack for?

• Medium game hunters targeting feral goats, pigs, fallow deer, chital deer, and roe deer — requires the maximum penetration capability of the .243 Winchester platform, utilizing a heavy-for-calibre 100-grain bonded soft point projectile leaving the muzzle at 910 m/s to retain over 90% of its mass through dense tissue.
• Hunters pursuing wild dogs with a .243 Winchester centerfire rifle — benefits from 2,691 Joules of muzzle energy and a 0.261 G1 ballistic coefficient optimized for rapid, reliable knockdown within a standard hunting envelope out to 200–300 metres.

Less suitable for: Hunting beyond 300 to 400 metres where a higher-BC, polymer-tipped, or boat-tail streamline hunting round better resists wind drift; or hunting heavy game like large Sambar deer, red deer stags, and scrub bulls that require larger calibres such as .270 Win, .308 Win, or .30-06.
