Redding Full Length Die Set Custom Series for Bottleneck Cases .300 PRC

Redding's Full Length Die Set Custom Series for bottleneck cases in .300 PRC gives you the precision tooling you need to load match-grade ammunition for this modern long-range magnum. This two-die set handles both the critical resizing and bullet seating operations that define cartridge quality and chamber fit. Whether you're prepping rounds for a new build, a custom rifle, or stepping up your reloading game, Redding's reputation for tight tolerances and consistent output makes this an investment in ammo that shoots.

The full length resizing die is fitted with a decapping rod assembly and neck expander button, which allows you to work with fired brass and bring it back to SAAMI specification. The matching seating die includes a built-in bullet guide and crimp ring, plus the proper seating plug sized for .300 PRC, so you get consistent bullet seating depth without guesswork. Redding manufactures these dies from premium alloy steels and holds them to tolerances so tight that your loaded ammunition will chamber reliably in any standard .300 PRC chamber, regardless of rifle action.

Every die is heat-treated in a controlled atmosphere, hand-polished for smooth operation, ultrasonically cleaned, and individually inspected before it ships. The included die box serves triple duty: it holds and organizes your dies, stores your shellholder, and comes packed with a spare decapping pin and hex wrench. Both dies use the industry-standard 7/8-14 threading, so they'll fit any standard reloading press.

Specifications

Frequently Asked Questions

Will these dies work in my reloading press?

Yes—Redding dies use the industry-standard 7/8-14 threaded bodies, so they'll fit any standard reloading press (single stage, turret, or progressive).

What's the difference between a full length die set and other die types?

A full length die set resizes the entire cartridge case back to SAAMI specification, not just the neck. This is ideal for .300 PRC ammo because it ensures consistent chamber fit and reliable feeding, especially across different rifles. The included seating die then seats your bullet to precise depth with an integrated crimp.

Is this set suitable for .300 PRC hunting or competition loads?

Yes—Redding's precision tolerances and manufacturing process produce ammunition that will fit any standard .300 PRC chamber and shoot reliably in hunting, range, or match applications.

What's included in the box?

You get both dies, a die storage box (which doubles as an organized loading block), a spare decapping pin, a hex wrench, and a dedicated pocket in the box for your shellholder.
