The Redding 280 Ackley Improved full length sizing die is a core tool for reloaders working with 280 Ackley Improved brass. This die sizes the entire cartridge—neck and body—and includes a decapping assembly and expander ball, giving you everything you need to prepare fired cases for a fresh reload. Whether you're loading for a precision rifle or maintaining factory ammunition tolerances, a full length sizing die handles the fundamental first step of the reloading process.
Full length sizing is the standard approach for most rifle reloaders, especially those working with ammunition destined for different rifles or who prioritize consistency across larger batches. The included decapping assembly removes spent primers cleanly, while the expander ball establishes proper neck tension for your bullet seating operations downstream. Redding's reputation for precision machining means tight tolerances and reliable performance across reload cycles.
Setup matters with sizing dies. Redding recommends using a headspace gauge when you're dialing in your full length die—this ensures the die is positioned correctly in your press and confirms you're sizing cases to safe, consistent dimensions. A few minutes of careful setup saves headaches and delivers repeatable results run after run.
