Redding 7Mm Remington Magnum Competition Bushing Neck Die Set

The Redding 7mm Remington Magnum Competition Bushing Neck Die Set is built for reloaders who demand precision and consistency in their cartridge prep. This three-die set pairs a competition-grade bushing neck sizing die, a full-length body die, and a competition bullet seater—giving you the tools to produce match-grade ammunition tailored to your rifle's chamber and your exacting standards.

Neck sizing with a bushing die lets you control exactly how much neck tension you apply to each round, which is critical for competitive shooting and precision hunting where velocity consistency matters. The bushing system works by completely supporting and aligning your case neck before sizing begins. As the case moves up into the die, it stays cradled in a tight sleeve while the bushing self-centers on the neck and does the work. The decapping rod rides on internal die surfaces for alignment precision comparable to a firing pin—no wobble, no runout. A micrometer adjustment on the bushing position gives you repeatable, fine control over neck length and sizing depth.

The body die handles full-length resizing and shoulder bump separately, so it won't touch your carefully sized neck. The competition bullet seater uses a floating stem design with ultra-tight tolerances: the bullet guide and seating stem fit so precisely that the stem actually floats during the seating stroke, centering the bullet on the cartridge centerline for better runout and more predictable chamber fit.

Bushings and shellholder are sold separately, so you'll choose the exact bushing size for your brass and the holder that matches your press. Built for reloaders running 7mm Remington Magnum who are serious about ES/SD and shot-to-shot consistency.

Frequently Asked Questions

Why use a bushing neck die instead of standard sizing?

A bushing die lets you control the amount of neck tension applied to your brass independent of the die itself. You choose the bushing size for your specific chamber and brass, giving you consistent neck pressure on every round. This is why competitive and precision shooters prefer them—better velocity ES/SD and tighter groups.

What bushings and shellholder do I need?

Bushings and shellholder are sold separately. You'll need to measure your fired case neck to select the correct bushing size for your chamber, and choose a shellholder that fits your press. Redding and other manufacturers offer bushing sizing guides to help you pick the right size.

Does this die set work with my Redding press?

These dies are designed for Redding presses and compatible equipment using standard press mounting. Confirm that your press accepts standard die threads and has the correct shellholder compatibility before purchasing.

How does the floating seating stem improve bullet seating?

The floating stem centers itself on the bullet during seating, aligning the bullet to the cartridge centerline rather than relying on the case mouth or die bore alone. This reduces runout and promotes more consistent chamber fit and ballistics, especially important for long-range and competitive loads.
