Redding 338 Lapua Magnum Body Die

The Redding 338 Lapua Magnum Body Die is a precision reloading die built for handloaders working up match-grade ammunition or managing brass through multiple firing cycles. Unlike full-length sizing dies that resize neck and body together, this body die focuses on what matters after brass has been fired and fired again: restoring proper body dimensions and bumping the shoulder back into spec without touching the neck. If your 338 Lapua brass has gotten picky about chambering, a body die is often the answer.

Long-range and precision rifle shooters who fireform or load for tight tolerances know that case necks can handle multiple firings without degradation—but case bodies and shoulders gradually work-harden and expand. A body die gives you surgical control: resize the body, set the shoulder position dead-on for reliable feeding, then move the brass to a separate neck die to fine-tune neck tension to your specification. It's a two-step process, but it beats scrapping brass that still has good life left in it.

Redding body dies are built without internal parts, keeping them simple and durable. They integrate into your existing die progression without fuss. This die is sold separately, so you'll pair it with a Redding 338 Lapua neck die to complete the sizing sequence—a straightforward workflow that handloaders have relied on for decades.

Frequently Asked Questions

Do I need a separate neck die to use this body die?

Yes. The body die resizes only the body and shoulder, leaving the neck untouched. After using the body die, you'll run brass through a 338 Lapua neck die to achieve proper neck tension and complete the sizing process.

When should I use a body die instead of a standard full-length die?

A body die is best for brass that has been fired multiple times and has become difficult to chamber. It allows you to resize the body and shoulder without over-working the neck, extending brass life and giving you tighter control over neck tension when paired with a separate neck die.

Is this die compatible with standard reloading presses?

The specifications provided do not include press compatibility details. Consult Redding's website or contact us to confirm compatibility with your press setup.

Can I use a body die for fireforming or wildcat loads?

Yes, body dies are commonly used in precision and long-range handloading workflows, including fireforming applications, because they let you control case body and shoulder dimensions independently from neck sizing.
