RCBS 280 Ackley Improved Full Length Die Set 2-Die Reloading Kit

The RCBS 280 Ackley Improved Full Length Die Set is a two-die reloading kit built for bottleneck cases, sized to SAAMI minimum cartridge dimensions with precision headspace tolerances. The full-length sizer die includes an expander-decapping unit that sizes, de-primes, and expands the neck in a single operation, while the seater die uses a bullet seater plug and a built-in roll crimper for a secure finish.

Both dies are vented to prevent case damage from trapped air and lubricant, and the minimum-tolerance headspace helps maintain case body length integrity through repeated loading. The set is intended for handloaders working with 280 Ackley Improved cartridges.
