Hornady Custom Grade Series IV Neck Sizer Die for 22 K-Hornet - Model 046066

The Hornady Custom Grade Series IV Neck Sizer Die for 22 K-Hornet is built for precision reloaders who want to squeeze every bit of accuracy out of their bolt-action rifle. Unlike full-length sizing dies that resize the entire case, a neck sizer die works only on the case neck—the part that actually grips your bullet. This targeted approach reduces unnecessary work-hardening of your brass, which translates to longer case life and more reloads before you need to retire good brass.

Neck sizing is ideal if you're loading ammunition for a bolt-action rifle and want to maintain tight chamber fits. When you size only the neck, you preserve the original body dimensions of your cases, which can improve concentricity—the alignment between your bullet and bore. Better alignment means better accuracy downrange and more consistent shot placement, whether you're developing loads for hunting or precision target work.

This die is part of Hornady's Custom Grade Series IV line, engineered to exacting standards for handloaders who demand reliability and consistency. Important note: neck sizing dies are specifically designed for bolt-action rifles. If you're loading for semi-automatic, lever-action, or pump-action rifles, those platforms typically require a full-length resizing die to ensure reliable feeding and extraction.

Frequently Asked Questions

Can I use a neck sizer die in my semi-automatic rifle?

No. Neck sizing dies are designed for bolt-action rifles only. Semi-automatic, lever-action, and pump-action rifles require a full-length resizing die to ensure proper feeding, extraction, and reliable function.

How does neck sizing improve accuracy?

A neck sizer die resizes only the case neck, preserving the body dimensions of your brass. This helps maintain tighter tolerances and improves bullet concentricity—how well the bullet aligns with the bore—which contributes to more consistent and accurate shot placement.

Will neck sizing help my brass last longer?

Yes. Because neck sizing involves less overall case manipulation than full-length sizing, your brass experiences less work-hardening and can typically withstand more reload cycles before reaching the end of its service life.
