Lee Precision 28 Nosler Custom Factory Crimp Die

A Lee Precision 28 Nosler Custom Factory Crimp Die is a specialized reloading die designed to deliver the uniform bullet seating and consistent pressure that serious handloaders need for tight groups and reliable performance. Whether you're loading for competition, precision hunting, or high-volume range work, a quality crimp die is one of the most effective—and often overlooked—tools for tightening your ammunition's accuracy potential.

The Lee Factory Crimp Die works differently than a standard seating die. Instead of relying on a sizing collar, it uses a collet mechanism that squeezes the case mouth firmly into the bullet's crimp groove. This approach delivers a more secure hold than conventional methods, which means pressure builds more uniformly inside the case before the bullet even begins to move. The result is a tighter, more predictable pressure curve and less shot-to-shot velocity variation—both of which translate directly to smaller groups and more reliable ballistics downrange.

What makes the design particularly practical is that it works effectively even on bullets without a crimp groove. That flexibility means you're not locked into specific bullet styles and can focus on finding the most accurate load for your 28 Nosler without compromising on crimp quality. The die is compatible with all standard 7/8"-14 reloading presses, so it integrates seamlessly into existing setups. Note that a shellholder is sold separately.

Frequently Asked Questions

What presses will this crimp die fit?

The Lee Precision 28 Nosler Custom Factory Crimp Die is compatible with all reloading presses that accept standard 7/8"-14 dies, which covers the vast majority of single-stage and progressive press models on the market.

Do I need bullets with a crimp groove for this die to work?

No. While the collet crimps most effectively into a crimp groove when one is present, the die is designed to deliver a firm crimp even on bullets without a groove, giving you more flexibility in bullet selection.

Is a shellholder included?

No, the shellholder is sold separately. You'll need a 28 Nosler shellholder to use this die.

How does a crimp die improve accuracy?

A firm crimp prevents the bullet from moving under pressure, which means chamber pressure builds more uniformly and reaches a higher, more consistent level before bullet movement begins. This uniform pressure curve reduces velocity variation between shots, leading to tighter groups and more predictable ballistics.
