Redding Series A Neck Sizing Die for Bottleneck Cases .308 Win/.307 Win

The Redding Series A neck sizing die for .308 Win and .307 Win bottleneck cases is a precision reloading die built for shooters who want reliable, accurate ammunition without paying for features they don't need. Redding's Series A line delivers the same manufacturing excellence as their premium dies—precision machining, heat treatment, and hand polishing—at a more accessible price point thanks to efficient production. If you're loading .308 Winchester or .307 Winchester for hunting, match shooting, or general practice, this neck die resizes the case shoulder and neck while leaving the body untouched, allowing you to preserve case life and maintain tight tolerances across multiple reloads.

The die comes equipped with a decapping rod assembly and neck expander button, so you can deprime and resize in a single stroke. Redding machines every die on Hardinge Super-Precision lathes capable of holding industry-leading tolerances, then heat-treats them in atmospherically controlled furnaces and hand-polishes each one for smooth operation. That process ensures your ammunition will properly fit any standard SAAMI chamber regardless of your rifle's action type. The 7/8-14 threaded body is the industry standard, compatible with any standard reloading press.

The die ships in a handy storage box that doubles as a cartridge loading block. Inside you'll find a spare decapping pin, hex wrench, and a slot for your shellholder—everything you need to get started without hunting down extras. If you're serious about reloading .308 Winchester or .307 Winchester brass, Redding Series A dies offer the precision and durability to produce match-grade ammunition year after year.

Frequently Asked Questions

What does a neck sizing die do?

A neck sizing die resizes only the shoulder and neck of the case while leaving the body and web untouched. This approach preserves case life by reducing the amount of work-hardening in the brass and allows you to reload the same cases many more times compared to full-length sizing.

Will this die work with my reloading press?

The Redding Series A die uses the industry-standard 7/8-14 thread, which fits any standard reloading press with a standard die station. Confirm your press accepts standard dies before purchasing.

Is the .308 Winchester the same as .307 Winchester?

No—these are two different cartridges. This die is sized for both .308 Win and .307 Win cases. Make sure you're using the correct cartridge for your rifle, as they are not interchangeable.

What's included in the box?

The die ships with a decapping rod assembly, neck expander button, spare decapping pin, hex wrench, and a storage box that functions as a cartridge loading block and includes a slot for your shellholder.
