Weatherby .280 Ackley Improved 139gr BTHP Hammer Bullet Ammo – 20 Rounds

Push the limits of long-range rifle performance with Weatherby .280 Ackley Improved ammunition loaded with 139-grain Hammer Bullet BTHP projectiles. Launching at a blazing 3,050 fps, this premium hunting load is purpose-built for flat-shooting accuracy and devastating terminal performance at extended distances.

Hammer Bullets are precision-turned on a CNC lathe from a proprietary solid copper blend, delivering exceptional consistency that mass-produced cup-and-core bullets simply can’t match. Every bullet is individually weighed and micrometer-measured during production, ensuring match-grade uniformity from round to round. The hollow point design initiates rapid, reliable expansion on impact — shedding petals immediately while retaining the remainder of the shank intact with a blunt nose profile for an optimal wound channel and deep penetration.

The .280 Ackley Improved cartridge builds on the proven .280 Remington by steepening the shoulder angle to 40 degrees, increasing powder capacity and delivering superior velocity with reduced case stretch. Combined with Weatherby’s renowned commitment to ballistic performance, this load represents one of the finest factory-loaded hunting cartridges available today.

Perfect for elk, deer, and other big game hunting at all practical rifle ranges, this 20-round box gives serious hunters a premium, consistent option for their .280 AI chambered rifles.
