L.E. Wilson Bushing Type Full Length Sizing Die 284 Win
The L.E. Wilson Bushing Type Full Length Sizing Die for 284 Win gives reloaders precision neck control without the hassle of separate neck-sizing operations. This full-length sizing die uses interchangeable bushings to dial in your exact neck tension while simultaneously sizing the case shoulder and body. It's built around Wilson's proven design philosophy: leave the bottom 3/16" of the case neck unsized, a practice many serious handloaders swear by for improved accuracy and brass longevity.
If you've shot Wilson's dedicated neck-sizing dies and loved the approach but need full-length sizing capability, this die bridges that gap. The bushing system lets you swap neck bushings (sold separately—Wilson and Redding bushings both fit) to fine-tune neck fit to your loaded rounds, without resizing the entire neck down to the shoulder. That selective approach reduces work-hardening and means your cases stay in the game longer.
The die itself is machined from hardened steel to Wilson's specs—tougher than Grade 8 fastener material—with stainless components that won't rust or corrode. It comes with an adjustable depth decapping rod and an extra decapping punch, so you're ready to start deprimming right away. The included Wilson lock nut handles standard 7/8"-14 reloading press threads. Just remember: neck bushings are sold separately, so plan your purchase accordingly.

Frequently Asked Questions
What's the difference between this die and a standard full-length sizing die?
The Wilson bushing-type design sizes your case shoulder and body while deliberately leaving the bottom 3/16" of the neck unsized. This partial neck approach reduces case work-hardening and is preferred by many shooters for improved accuracy and case life. You control neck tension separately via interchangeable bushings rather than relying on a fixed expander.
Do neck bushings come with the die?
No. Neck bushings are sold separately. However, the die accepts both L.E. Wilson and Redding brand bushings, so you have options when sourcing them.
What press does this die fit?
The die is threaded for standard 7/8"-14 reloading press threads and includes a Wilson lock nut, so it will work with any conventional single-stage or progressive press using that standard threading.
Is the decapping rod adjustable?
Yes. The die includes an adjustable depth decapping rod, plus an extra decapping punch, so you can fine-tune primer pocket depth and have a backup punch on hand.
