Description
If you're chasing tight groups out of your 6.5 Grendel, this is the kind of tooling that separates good handloads from great ones. Redding built the Competition Bushing Neck Die Set for folks who neck size their brass and want the precision to back it up. It's a three-die set that includes the Competition Bushing Neck Sizing Die, a Body Die, and the Competition Seating Die, all machined to the tight tolerances Redding is known for.
What the Three 6.5 Grendel Dies Actually Do
The Competition Bushing Neck Sizing Die is where the magic happens. The case is fully supported and aligned inside a close-fitting sliding sleeve before the bushing ever touches the neck, so the sizing bushing self-centers on the case and keeps runout to a minimum. A micrometer adjustment lets you dial in exactly how much of the neck gets sized, which makes partial neck sizing a breeze. The Body Die handles full-length body resizing and bumps the shoulder back when cases start getting sticky to chamber, without touching the neck. The Competition Seating Die uses a sliding bullet guide and a micrometer top so you can set seating depth repeatably and hold bullet seating to around a thousandth.
Dialing In Neck Tension with the Grendel Bushing System
Because the neck die runs on interchangeable bushings available in .001 inch steps, you get to decide your exact neck tension rather than settling for whatever a standard die gives you. For 6.5 Grendel, Redding lists a usable bushing range of roughly .283 to .291 inches, so you can tune to your brass and bullet combo. Keep in mind this set is built around sorted or neck-turned brass, so it skips the size button entirely. A decapping pin retainer is included to let you size necks without that button.
This set shines when paired with consistent brass. Bushings and a #12 shellholder are sold separately, so grab the sizes that match your loads and you'll be ready to build match-grade ammo on your single-stage press.

Frequently Asked Questions
Do I need to buy bushings separately for this 6.5 Grendel die set?
Yes. The Competition Bushing Neck Sizing Die uses interchangeable bushings to set your neck tension, and those are not included in the set. For 6.5 Grendel, Redding lists a usable range of roughly .283 to .291 inches, so pick the size that matches your brass and bullet combination.
Is a shellholder included with the Redding 58478 die set?
No, the shellholder is sold separately. The 6.5 Grendel uses a #12 standard shellholder, and a #12 competition shellholder is also available if you want to pair it with the competition seating die.
Does this set come with a size button?
It does not. The Competition Bushing Neck Die Set is designed for reloaders who sort their brass for neck thickness or neck turn their cases, so the bushing handles sizing without a button. A decapping pin retainer is supplied so you can size necks without one.
What's the difference between the Body Die and neck sizing in this set?
The Competition Bushing Neck Sizing Die only works the neck and leaves the case body untouched, which is great for brass fired in your own chamber. The Body Die steps in to full-length size the body and bump the shoulder back when cases get tight to chamber after repeated firings. Using them together keeps your brass running smoothly while preserving accuracy.
