The Redding 6mm GT neck sizing die set is purpose-built for reloaders who want precision control over case neck runout and concentricity. This two-die set lets you resize only the neck of your bottleneck cases—avoiding unnecessary full-length sizing and the associated work-hardening that can shorten case life. If you're chasing accuracy in match, hunting, or precision rifle competitions, a neck sizing approach with quality dies like these can help you hold tighter groups and extend case longevity across multiple firings.
The set includes a neck resizing die with an integral decapping rod and neck expander button, which gently opens the neck to accept your bullet without disturbing case body dimensions. The seating die features a built-in bullet guide and crimp ring, along with the correct seating plug for the 6mm GT cartridge, so you can seat bullets consistently and apply a light crimp in one smooth stroke. Both dies are machined to Redding's exacting standards for fit and concentricity.
Redding dies are a reloader's workhorse—they're robust, straightforward to use, and built to last through thousands of rounds. Whether you're loading match ammo for a precision rifle, preparing hunting loads, or simply wanting to get the most life out of your brass, a dedicated neck sizing die set keeps variables under control and keeps your reloading operation efficient. Note that you'll need a compatible shell holder (sold separately) to secure your cases during sizing and seating.

Neck sizing dies resize only the neck of the case, leaving the body and shoulder untouched. This preserves case dimensions and can extend case life by avoiding repeated work-hardening from full-length sizing. Many precision rifle and match loaders prefer neck sizing for consistency and efficiency.
Yes. This die set does not include a shell holder. You'll need to purchase one separately that matches your press and cartridge specification. Redding shell holders are available in various sizes to fit different cartridge families.
These dies are compatible with standard single-stage, turret, and progressive presses that accept standard die threads. Always consult your press manual and die instructions to confirm proper setup and compatibility.
The neck expander button gently opens the inside of the case neck to a precise dimension, preparing it to accept a bullet without excessive sizing force. This helps maintain concentricity and reduces neck stress during the seating process.
