Redding 280 Ackley Improved Full Length Die Set

The Redding 280 Ackley Improved full length die set gives you everything needed to resize and seat .280 Ackley Improved cartridges on your reloading bench. This matched pair includes both the full length sizing die and the standard seating die—two of the three essential tools in any rifle reloading setup. If you're working up loads for a .280 AI hunting rifle, precision target rig, or keeping brass in service after multiple firings, a full length die set is the foundation of consistent, safe ammunition.

Redding dies are known for attention to detail and reliable performance across thousands of reloading cycles. The full length sizing die restores fired brass to factory dimensions, ensuring smooth feeding and reliable chamber fit in your .280 AI rifle. The seating die lets you dial in bullet seating depth with precision—critical for both accuracy and safe pressures.

This set is designed for reloaders who want a turnkey solution: both dies come ready to mount in a standard reloading press. If you're new to the .280 Ackley Improved or expanding an existing setup, verify your press compatibility and refer to current load data before beginning.
