Redding 6Mm Cm Competition Bushing Neck Die Set
The Redding 6mm CM Competition Bushing Neck Die Set is purpose-built for precision rifle reloaders who demand consistency in neck sizing and bullet seating. This three-die set brings competition-grade accuracy to 6mm Creedmoor handloading, combining a competition bushing neck sizing die, a full-length body die, and a competition bullet seater—each engineered to tighter tolerances than standard dies. If you're chasing tight groups and minimal case runout, this is the system that separates serious reloaders from casual ones.
The Competition Bushing Neck Sizing Die is the workhorse here. It keeps your case completely supported and aligned during the entire sizing stroke, preventing the neck from shifting or cocking—a common source of runout. The case slides into a tightly chambered sleeve and remains locked in position as it moves upward into the sizing bushing. The bushing itself self-centers on your case neck, and the decapping rod is guided with the precision of a firing pin channel. The micrometer adjustment lets you dial in exactly how much neck material gets sized, giving you repeatable, measurable control over neck tension run to run.
The Body Die handles full-length resizing of the case body and shoulder bump without touching the already-sized neck—that's the whole point of a bushing neck die system. The Competition Bullet Seater finishes the job with a floating seating stem held to such exacting tolerances that the stem actually floats within its guide. That precision fit means bullet runout stays low and seating depth becomes rock-solid repeatable.
Note: Bushings and shellholders are sold separately, so check your 6mm CM requirements before ordering. This set is built for handloaders who understand that competition-grade reloading is an investment in velocity consistency and case life.

Frequently Asked Questions
What dies are included in this 6mm CM set?
The set includes three dies: a Competition Bushing Neck Sizing Die with micrometer adjustment, a Body Die for full-length case resizing and shoulder bumping, and a Competition Bullet Seater with micrometer adjustment for precise seating depth control.
Do I need to buy bushings and shellholders separately?
Yes. Bushings and shellholders are sold separately, so you'll need to order those items based on your 6mm CM press setup and specifications.
How does the Competition Bushing Neck Die reduce runout?
The die supports and aligns the cartridge case completely before and during sizing. The case remains locked in a tightly chambered sliding sleeve, and the sizing bushing self-centers on the case neck. This eliminates the case shifting or cocking that causes runout in standard dies.
Is this die set suitable for competition or precision hunting?
Yes. The competition-grade design—with micrometer adjustments, tight manufacturing tolerances, and floating seating stem precision—is intended for reloaders pursuing the consistency and accuracy demanded by precision rifle competition and long-range hunting.
