The Nosler Trophy Grade .280 Ackley Improved 160-grain AccuBond Spitzer Polymer Tip Brass 20-round box is a premium centerfire rifle cartridge engineered specifically for medium-to-large big game hunting, long-range elk management, and mountain big game pursuit. A primary challenge when hunting at extended ranges is maintaining projectile integrity and achieving deep, lethal penetration across a wide window of impact velocities. Nosler resolves these performance limitations by pairing its custom prepped reloadable brass cases with the bonded 160-grain AccuBond® Spitzer bullet, delivering high ballistic efficiency, flat downrange trajectories, and reliable controlled expansion without core separation.
The primary technical advantage centers on Nosler’s 160-grain AccuBond projectile design integrated with the efficient .280 Ackley Improved case geometry. Featuring a sleek white polymer tip, boat-tail profile, and tangent ogive yielding a 0.531 G1 ballistic coefficient, the bullet significantly minimizes aerodynamic drag and crosswind deflection. The internal architecture utilizes a proprietary bonding process that chemically welds the lead-alloy core to the thick copper jacket. This bonded construction prevents jacket-core separation upon high-velocity impact, ensuring the projectile retains high mass while expanding uniformly to create a deep, destructive wound channel through heavy muscle tissue and major bone.
Launching its 160-grain AccuBond® bullet at a factory-rated 2,875 FPS muzzle velocity, this Trophy Grade loading leverages the .280 Ackley Improved’s sharp 40-degree shoulder angle to promote efficient propellant burn and minimal case stretch. Assembled using Nosler’s custom prepped virgin brass cases—which are weight-sorted, chamfered, and flash-hole inspected—alongside clean-burning powders and non-corrosive Boxer primers, the cartridge guarantees uniform chamber pressure curves and shot-to-shot consistency. It serves as an elite choice for hunting elk, mule deer, moose, caribou, and bighorn sheep.
