The Redding Competition Bushing Neck Die for .223 Rem is purpose-built for precision reloaders who demand exacting control over neck sizing. If you're prepping match-grade ammunition for competition shooting and want to move beyond standard sizing buttons, this die delivers the repeatability and customization that separates competitive loads from factory fodder.
The engineering here is thoughtful: your cartridge case sits fully supported and precisely aligned in a tight chambered sleeve before sizing even begins. As the case moves upward, it stays cradled in that sleeve while the sizing bushing self-centers on the neck—eliminating the wobble and inconsistency that can creep in with less rigid setups. The decapping rod rides on internal die geometry for stable alignment, similar to how a firing pin seats in a rifle. That rigidity translates to shot-to-shot neck sizing uniformity.
What sets this die apart is the micrometer adjustment on the bushing position. Rather than guessing or trial-and-error, you dial in exactly how much neck diameter you want to resize—critical when you're working with prepped brass and handloading for tight groups. The design intentionally omits a sizing button (though Redding sells button kits separately if you change your mind), giving you complete freedom in how aggressively you size your necks.
This is a .223 Rem–specific die, built for shooters who already understand case prep and want precision tools to match their discipline. Bushings and shellholders are sold separately, so plan accordingly when you order.
| Caliber | .223 Rem |
| Type | Bushing Neck Die |
| Manufacturer | Redding |
| Bushings | Sold separately |
| Shellholders | Sold separately |
Yes. Bushings and shellholders are not included with this die and are sold separately. You'll need the correct bushing size for your desired neck diameter and a compatible shellholder for your press.
This die is designed without a sizing button built in. However, Redding offers carbide sizing button kits available separately if you decide you want one.
This die is made for competition reloaders and precision handloaders who have already cleaned and prepped their brass and want tight control over neck sizing. If you're loading match ammo and seeking consistency, this is your tool. Casual or high-volume reloaders may find standard sizing dies more convenient.
As a standard Redding die, it will fit presses with standard 7/8-inch–14 thread dies (the industry norm). Verify your press accepts standard dies, and ensure you have the correct shellholder for your setup.
