The Hornady .323 8mm 180 Grain ECX Bullets (50 Pack) are monolithic copper alloy reloading projectiles engineered for medium to large game hunting. Designed for seamless seating and feeding in .323-calibre cartridges, such as the traditional 8×57mm IS (8×57 JS), 8×68mm S, and 8mm Remington Magnum, these non-lead projectiles feature aerodynamic driving bands and a flat polymer expansion tip. On impact, the polymer tip drives into the hollow nose cavity to initiate controlled, uniform mushrooming, while the one-piece construction retains up to 95% of its weight without core-jacket separation.

• Lead-Free Monolithic Alloy: Constructed from a solid one-piece copper alloy to ensure deep penetration and up to 95% weight retention across game weighing between 23 kg and 680 kg.
• Flat Polymer Tip: Initiates rapid expansion across varied impact velocities while maintaining the profile necessary for short-to-medium woodland shooting ranges.
• Grooved Driving Bands: Circumferential relief bands reduce bore friction and bearing surface resistance, improving velocity retention and gas sealing.

Who is the Hornady 8mm 180 Grain ECX Bullet for?

• Hunters targeting Australian feral boar and deer with 8mm rifles — delivers up to 95% weight retention in an 8mm (.323") 180-grain projectile, ensuring controlled expansion and deep terminal penetration on tough feral pigs, fallow, red, and sambar deer at short-to-moderate bush stalking distances.
• Handloaders seeking non-lead monolithic hunting projectiles in .323 diameter — provides a dedicated monolithic 8mm rifle reloading component with an aerodynamic relief-grooved shank and a 0.257 G1 ballistic coefficient to reduce bearing-surface friction in modern .323-bore chambers.

Less suitable for: Long-range hunting beyond 300 metres, where the 0.257 G1 ballistic coefficient drops velocity below the threshold required for hydraulic expansion—opt for a high-BC, streamlined boattail hunting projectile instead. It is also strictly incompatible with historical .318-bore 8mm Mauser (8×57 I) barrels, which require dedicated .318" diameter bullets.
