The Weatherby 280 Ackley Improved unprimed brass cases deliver the precision foundation needed for maximum performance from this popular wildcat cartridge. Each case features Weatherby's quality brass construction designed to handle the increased pressures and velocities that make the 280 AI a standout performer for long-range hunting and precision shooting.

What Makes This Different

Weatherby brass cases undergo rigorous quality control to ensure consistent wall thickness and proper headspace dimensions. The 280 Ackley Improved chamber requires brass that can handle approximately 200-300 fps velocity increases over standard 280 Remington loads. These cases feature the sharp shoulder angle and minimal body taper that defines the Ackley Improved design, maximizing powder capacity while maintaining safe pressure levels.
