Hornady Superformance .308 Win 150gr CX Polymer Tip Lead-Free Ammo - 20 Rounds

Hornady Superformance .308 Win 150gr CX ammunition delivers velocity gains of 100–200 fps over standard loads without cranking up chamber pressure or felt recoil. Built around Hornady's CX polymer-tipped, lead-free bullet, this cartridge is engineered for hunters who need flat trajectories and consistent terminal performance across hunting seasons and temperature swings. The Superformance line uses progressive powders that extract maximum energy from your .308 Winchester, making it an excellent choice for medium to large game at extended distances.

The CX bullet is a fully copper construction—no lead core—which means cleaner shooting and compliance with non-toxic ammunition restrictions in many hunting regions. The polymer tip initiates reliable expansion while the boat-tail design improves ballistic coefficient for better energy retention downrange. Hornady loads these rounds into premium brass with match-grade primers, so you get the consistency you'd expect from factory ammunition without the batch-to-batch guesswork.

If you reload or handload, this cartridge also serves as reference for what's possible with the right powder and bullet pairing in a .308 platform. For hunters running bolt-action or semi-auto rifles in this caliber, Superformance ammunition cuts down the gap between factory ammo and custom handloads—velocity and accuracy without the labor or expense.
