Description
If you're chasing single-hole groups out of your 6.5 Grendel, this Redding Type S-Match Bushing Neck Die Set is built for exactly that kind of work. This is the three-die set under Redding part number 38478, and it's aimed at reloaders who neck size their brass and want fine control over neck tension rather than running a standard one-size-fits-all die. The package pulls together Redding's bushing neck die, a competition seating die, and a body die so you can tune every stage of your reloading process.
What the Type S-Match Neck Die Set Does Differently
The heart of this set is the Type S bushing neck sizing die. Instead of sizing the neck a fixed amount, it uses interchangeable bushings sold in .001 inch increments, so you dial in the exact neck tension your rifle and bullet combination like best. The bushings self-center on the case neck to help with concentricity, and the adjustable decapping rod lets you position the bushing to size only part of the neck length if you want to leave a portion untouched. The decapping rod comes with a standard sizing button, and a decapping pin retainer is included so you can skip the button entirely if you sort or turn your necks.
Why Grendel Reloaders Reach for This Redding Set
The Competition Seating Die is where the precision really shows up. It uses a spring-loaded sliding sleeve that guides and aligns the case and bullet before seating begins, and the micrometer head adjusts seating depth in clean .001 inch clicks so you can repeat a load exactly. The seating stem is precision ground to match bullet diameter for straight, consistent seating. Worth noting, this competition seating die isn't intended for compressed loads.
Rounding Out the Three-Die Setup
The included body die handles full length body resizing and shoulder bump without touching the neck, which is handy once brass has been fired and neck sized a few times and starts getting stubborn to chamber. For 6.5 Grendel, this die set runs bushings in the .283 to .291 range and uses the #12 shellholder. Keep in mind bushings and the shellholder are sold separately, so pick up the right bushing for your brass before your first session.

Frequently Asked Questions
Does the Type S-Match Bushing Neck Die Set come with bushings?
No, bushings are sold separately so you can match the exact neck tension you want. For 6.5 Grendel, Redding lists a usable bushing range of .283 to .291 inches. The standard way to size a bushing is to measure your loaded neck diameter and subtract about .001 inch.
Is this a two-die or three-die set?
This is the three-die set under Redding part number 38478. It includes the Type S bushing neck sizing die, a Competition Seating Die, and a body die. That makes it different from the two-die Full Length Match set, which carries part number 36478.
Do I need a shellholder for the 6.5 Grendel version?
Yes, and it's not included in the box. The 6.5 Grendel uses the Redding #12 shellholder. If you already reload other cartridges you may have the right one on hand, otherwise pick one up before your first loading session.
Can the Competition Seating Die handle compressed loads?
No, Redding notes the Competition Seating Die is not intended for compressed loads. If you're running a heavy compressed charge, you'll want a standard seating die for that step. For typical match loads, the micrometer competition seater gives you excellent repeatability and alignment.
