The Redding 6mm GT neck sizing die is purpose-built for reloaders working with modern bottleneck cases who want precision and consistency without full-length resizing. This Series C die is designed specifically for the 6mm GT cartridge, offering the controlled neck expansion and sizing that match-grade shooters depend on for accuracy-focused handloading. If you're developing loads for long-range hunting or precision rifle work, a dedicated neck sizing die lets you maintain case dimensions and brass longevity while ensuring reliable chambering.
Neck sizing dies work differently than full-length dies: instead of resizing the entire case body, they focus on the neck area where the bullet sits. This approach reduces case working and extends case life—an important consideration if you're building premium ammunition or loading expensive brass multiple times. The Redding neck sizing die includes a decapping rod assembly and neck expander button, so you can deprime and size the neck in a single pass through your press.
Like all Redding reloading dies, this Series C unit is manufactured to tight tolerances and designed to work reliably across the range of pressures and velocity you'll encounter with 6mm GT loads. Keep in mind that you'll need a compatible shell holder (sold separately) to use this die in your press.

Neck sizing resizes only the neck of the case where the bullet engages, while full-length sizing resizes the entire case body. Neck sizing reduces case working and can extend case life significantly, making it popular for precision and match-grade reloading. Full-length sizing is more forgiving for mixed brass lots and semi-automatic rifles.
You'll need a compatible Redding shell holder, sold separately. Redding Shell Holder #1 is listed as compatible with this die.
Yes, the die includes a decapping rod assembly, so you can deprime and neck-size in a single pass through your press.
Neck sizing is a popular choice among precision rifle shooters and handloaders developing match-grade ammunition, as it maintains tight case-to-chamber dimensions without the working stress of full-length sizing. The Redding Series C design is manufactured to the tolerances that precision loading demands.
