The Redding 243 Winchester Competition Bushing Neck Die Set is purpose-built for competitive shooters and precision handloaders who demand consistency in every round. This three-die set includes a Competition Bushing Neck Sizing Die, a Body Die, and a Competition Bullet Seater—all engineered with the tight tolerances and adjustability that separate match-grade ammo from the rest. If you're loading for accuracy competitions, long-range hunting, or simply refuse to compromise on case prep, this is the system that delivers shot-to-shot uniformity.
The heart of this set is the bushing neck die, which uses a completely different approach than standard sizing. Your case neck is fully supported and aligned before sizing even begins, then stays secure in a snug sliding sleeve as it moves upward. The sizing bushing self-centers on the neck itself, and the decapping rod rides along internal die surfaces for the kind of precision alignment you'd expect from a firing pin guide. The micrometer adjustment lets you dial in exactly how much neck length gets sized—no guessing, no trial and error.
The Body Die handles full-length resizing of the case body and bumps the shoulder back just enough for reliable chambering, all without touching the neck you just finished preparing. The Competition Bullet Seater goes a step further with a floating seating stem system and tolerances so tight that the stem actually floats within its guide. That means consistent bullet alignment and runout control that translates directly to tighter groups.
Note that bushings and a shellholder are sold separately, so you'll need to source those based on your specific setup and desired neck clearance.

| Die Set Contents | Competition Bushing Neck Die, Body Die, Competition Bullet Seater |
| Adjustment Type | Micrometer (neck die and seating die) |

The set contains three dies: a Competition Bushing Neck Sizing Die with micrometer adjustment, a Body Die for full-length resizing and shoulder bumping, and a Competition Bullet Seater with micrometer adjustment and floating seating stem.
Yes. Bushings are sold separately, so you'll need to select the appropriate bushing size for your desired neck clearance and obtain a compatible shellholder as well.
The floating seating stem aligns the bullet concentrically with the case as it's seated, which helps control bullet runout and ensures consistent seating depth. Tight manufacturing tolerances allow the stem to float smoothly within its guide.
Absolutely. The micrometer adjustments on the neck die and seater, combined with the precision bushing neck sizing and floating seating stem, are designed specifically for competitive shooters who need match-grade ammunition with tight tolerances.
