Redding 280 Ackley Improved Bushing Full Length Die Set

The Redding 280 Ackley Improved Bushing Full Length Die Set brings precision handloading to your 280 AI brass with a two-die system designed for shooters who demand tight tolerances and consistent results. This set pairs a Type S Bushing Full Sizing Die with a Competition Bullet Seating Die—the same tools used by competitors and serious hunters who understand that case preparation and bullet seating are where accuracy is truly won.

The Type S Bushing Full Sizing Die handles full-length resizing while giving you direct control over case neck sizing through interchangeable bushings. Rather than a one-size-fits-all approach, you choose your own bushing to dial in neck tension exactly where you want it—critical for 280 AI loads where consistency matters. The Competition Bullet Seating Die takes concentricity seriously: a micrometer calibrated in .001" increments lets you dial in seating depth with rifle-range precision, while the floating seating stem reduces runout and ensures bullets are seated straight.

Whether you're loading for a custom 280 Ackley Improved build or fine-tuning an existing rig, this die set gives handloaders the control they need to produce match-grade ammunition without guesswork.

Frequently Asked Questions

What are interchangeable bushings and do I need multiple sizes?

The Type S bushing system lets you select the neck diameter that controls how tightly your sized case grips the bullet. You determine the bushing size based on your fired case necks and desired neck tension. The die set includes the capability to use different bushings; you may need to purchase additional bushing sizes separately depending on your brass and seating requirements.

Will this die set work with standard reloading presses?

Redding dies are designed to work with standard reloading presses that accept standard die threads. Confirm your press compatibility with your equipment manual or contact Redding if you have questions about your specific setup.

What's the advantage of the floating seating stem?

The floating seating stem reduces runout (bullet tilt) during the seating process by allowing the stem to center itself on the bullet naturally. This alignment helps keep bullets seated straight, which translates to better accuracy downrange—especially important for precision handloading.

Is this a full reloading die set with decapping?

This is a two-die set containing a sizing die and seating die. The sizing die handles full-length resizing; you'll need a separate decapping tool or universal decapper if primer removal is your first step.
