The revolutionary new Redding Competition Neck Sizing Die with interchangeable bushings brings an advanced level of precision to Competition Shooters.

Similar in design concept to our Competition Seating Die, the cartridge case is completely supported and aligned with the sizing bushing before the sizing process begins.

As the sizing process starts, the cartridge case remains supported in the tightly chambered, sliding sleeve as it moves upward while the resizing bushing self-centers on the case neck.

The decapping rod is maintained in precise alignment by using the internal parts of the die as a linear support much like that of a firing pin.

Meanwhile, the micrometer adjustment of the bushing position delivers precise control to the desired amount of neck length to be sized. Although this die was designed for use by Competition Shooters who have meticulously prepared their cartridge cases and do not wish to use a sizing button, carbide size button kits are available separately.

TO DETERMINE BUSHING SIZE
The proper bushing size can be easily determined by measuring the outside neck diameter of your loaded cartridges with a precision micrometer. Then, simply subtract .001" from the cartridge that had the smallest average neck diameter. See page 16 for complete explanation.

Moly coated bullets may require tighter necks and the use of bushings .001” or .002” smaller.

The Redding Competition Seating Die has quickly established itself as the “state of the art” in straight line bullet seaters.

This design, covered by U.S. Patent No. 4,862,567, has beat the concentricity problems inherent in all other seating dies of this type.

Tighter manufacturing tolerances have been made possible due to the details of the patented seating stem system. The bullet guide to seating stem fit is so precise that the seating stem can actually be demonstrated to “float” on a column of air. The seating stem is precision ground to exactly match bullet diameter. No seating die on the market is built to this level of precision. Alignment and accuracy are enhanced by the cartridge case and bullet being completely supported and aligned in a close fitting, precision ground sleeve before the bullet seating begins.

The micrometer is calibrated in .001" increments for precise seating depth and is infinitely adjustable (without clicks). The micrometer also has a “zero” set feature that allows you to zero the micrometer to your rifle or favorite seating depth.
