Redding Reloading Equipment
The Redding Neck Sizing Die for 7mm Rem Mag is a precision reloading die built to extend brass life and tighten accuracy on your bolt-action rifle. Unlike full-length sizing dies, a neck sizing die works only on the case neck—leaving the shoulder and body alone. This approach lets you reload the same brass multiple times in your own rifle while maintaining consistent chamber fit and minimizing dimensional changes that can degrade accuracy over time.
Redding neck sizing dies are machined from premium alloy steel on Hardinge Super-Precision lathes that hold some of the tightest tolerances in the reloading industry. Each die is heat-treated in controlled furnaces and hand-polished to ensure smooth, reliable operation through thousands of reloads. The result is a tool that resists wear, maintains its critical dimensions, and delivers the accuracy-focused reloader exactly what they need for consistent, repeatable ammunition.
One important note: neck sizing dies are caliber-specific and designed for single-rifle use. Because the shoulder and body aren't resized, fired cases should never be moved between rifles. This is the trade-off for the accuracy and brass longevity neck sizing provides. If you're handloading for a dedicated 7mm Rem Mag rifle and want to squeeze maximum performance from your brass, a neck sizing die is a worthwhile investment in your reloading bench.

A neck sizing die sizes only the case neck, leaving the shoulder and body untouched. Full-length dies resize the entire case. Neck sizing prolongs brass life and can improve accuracy when reloading for a dedicated rifle, but cases must stay in that same rifle since the shoulder isn't resized for chamber fit in other guns.
No. Neck sizing dies are designed for single-rifle use. Fired cases should never be interchanged between rifles when using a neck sizing die, because the shoulder and body dimensions aren't adjusted. Always reload neck-sized brass only in the rifle it was fired from.
By resizing only the neck and avoiding unnecessary working of the case body and shoulder, neck sizing reduces stress on the brass and allows more reloads before cases need to be retired. The exact number of reloads depends on your load, but brass life is typically extended compared to full-length sizing.
Yes. Redding neck sizing dies are ideal for bolt-action rifles, which are the typical platform for precision handloading where neck sizing delivers its best accuracy benefits.
