The Norma Oryx 8x57 JRS 196gr Bonded Soft Point Ammunition (MPN: 20180102) is factory-loaded hunting ammunition engineered specifically for break-action double rifles, Drillings, and combination firearms. Featuring Norma’s chemically bonded core-and-jacket construction, this 196-grain load eliminates jacket separation upon impact, delivering rapid yet controlled expansion with high weight retention. Tested out of a 610 mm (24 in) barrel, it achieves a muzzle velocity of 730 m/s and 3,384 J of muzzle energy, making it an effective bush and stalking round for Australian big-game applications.

Key Features

• Bonded Core Construction: Norma's proprietary chemical bonding fuses the lead core to the gilding metal jacket, retaining over 90% of its residual weight through dense muscle and bone.
• Controlled Terminal Performance: Engineered with a forward-tapering jacket that initiates prompt expansion while retaining the structural integrity needed for deep penetration.
• Downrange Energy Delivery: Produces 2,658 J of energy at 100 m and 2,063 J at 200 m, maintaining strong knock-down power at typical stalking distances.
• Dedicated Rimmed Case: Purpose-built with an extractor rim for positive extraction in break-action, double rifle, and falling-block actions.

Who is the Norma Oryx 8x57 JRS 196gr for?

• Sambar and red deer stalkers using break-action combination guns — Requires a heavy, bonded 196-grain projectile generating 3,384 J of muzzle energy to ensure deep penetration through heavy bone and high weight retention at timber ranges.
• Feral boar hunters operating at close to moderate distances — Leverages a 730 m/s muzzle velocity and a 145 m most recommended distance (MRD) in this 8x57 JRS hunting ammunition for fast expansion and high knockdown power inside dense cover.

Less suitable for: Long-range shooting beyond 300 m, where the 0.331 G1 ballistic coefficient causes significant drop and velocity loss (falling to 500 m/s at 300 m); hunters engaging game at extended distances require higher-BC boat-tail or polymer-tipped hunting rounds. It is mechanically unsuitable for standard bolt-action rifles chambered for rimless 8x57 JS / 8mm Mauser, which require standard rimless cartridges.
