Hornady Match Grade Dies give you total control over neck tension in the resizing process and feature interchangeable self-centering neck size bushings that eliminate the chance of over sizing your case necks and overworking the brass. Tight tolerances at the press translate into tighter groups at the range. The Hornady 545139 is specifically engineered for the .280 Ackley Improved cartridge and includes a full-length sizing die with bushing compatibility and an in-line bullet seating die.
New for 2025 the Click-Adjust Micrometer will now come factory installed on Hornady Match Grade seating dies. This micrometer allows you to precisely set bullet seating depth with click adjust .001″ increments as a quick and easy way to achieve benchrest accuracy and consistency. Match Grade seating dies are known for their ability to seat bullets perfectly straight, minimizing bullet runout and ensuring optimal bullet-to-bore alignment, with many Hornady seating dies featuring a floating bullet guide and an in-line seating system to achieve superior concentricity.
this two-die set provides the core reloading functions for producing exceptionally consistent .280 Ackley Improved ammunition. Note that interchangeable neck size bushings are sold separately.
