The Norma Bondstrike Extreme 6.5x55 Swedish Mauser (6.5x55 SE) 143gr factory-loaded ammunition is engineered for flat shooting and controlled expansion at medium to extended hunting ranges. Loaded with a 143-grain (9.27 g) polymer-tipped, boat-tail hunting projectile in reloadable brass cases, this load achieves a muzzle velocity of 830 m/s (2,723 ft/s) and a muzzle energy of 3,193 Joules from a 610 mm test barrel. The chemically bonded lead core and tapered jacket preserve bullet weight on impact, retaining 2,207 Joules of energy and a velocity of 690 m/s at 300 metres to secure reliable terminal upset on medium-to-large game.

• Aerodynamic Polymer Tip: Initiates rapid expansion on impact while reducing in-flight drag to maintain a 0.629 G1 ballistic coefficient.
• Chemically Bonded Core: Fuses the lead core to the jacket to prevent jacket-core separation and ensure high weight retention through target tissue.
• Match Boat-Tail Profile: Delivers long-range flight stability with a 0.313 G7 ballistic coefficient for reduced wind drift.
• Premium Reloadable Brass: Loaded into Norma factory brass cases manufactured to tight dimensional tolerances.

Who is the Norma 6.5x55 143gr Bondstrike Extreme 20 Pack for?

• Deer hunters targeting red, sambar, and fallow deer at extended ranges — Utilises a high 0.629 G1 ballistic coefficient and 143-grain bonded projectile to maintain 2,207 Joules of energy at 300 metres, delivering the deep penetration and flat trajectory required for large deer species.
• Field hunters pursuing feral pigs and goats with 6.5x55mm rifles — Launches at 830 m/s to achieve a 172-metre recommended zero, giving 6.5x55mm hunting ammunition users point-blank holdover efficiency and rapid terminal upset across open terrain.

Less suitable for: Rifles chambered in other 6.5mm cartridges (such as 6.5 Creedmoor or 6.5 PRC) due to chamber incompatibility, or heavy game hunting in extremely dense timber at close ranges under 50 metres, where traditional flat-nose or round-nose heavy-jacketed bullets are better suited to resist deflection.
