Redding 300 Aac Blackout Full Length Sizing Die$58.85
Availability: In Stock
The L.E. Wilson 300 AAC Blackout bushing full length sizing die gives reloaders precision control over neck tension while sizing the case body in a single stroke. Built from high-quality heat-treated steel hardened to L.E. Wilson specifications—tougher than Grade 8 bolts—this die is designed for shooters who demand accuracy and consistency on the bench and downrange. The bushing system lets you dial in exactly how much neck tension you want, a level of customization that standard dies simply don't offer.
What sets Wilson's bushing dies apart is their approach to the case neck itself. Rather than sizing the entire neck, these dies intentionally leave the bottom 3/16" of the case neck unsized. Many precision reloaders prefer this method because it reduces case work-hardening and can improve accuracy compared to full-neck sizing. You get repeatable, controlled neck sizing without the guesswork of trying to match a one-size-fits-all die to your specific brass.
The die comes ready to work: it includes an adjustable depth decapping rod and an extra decapping punch so you're not scrambling for replacements mid-session. The lock nut is L.E. Wilson manufactured and built to their specs for reliability. Stainless steel components resist corrosion and keep the die functioning smoothly over years of use. This is standard 7/8" reloading press compatible, so it fits any press in your setup. Note that neck bushings are sold separately; L.E. Wilson makes bushings sized specifically for this die, and Redding bushings will also fit if you prefer those.
The 300 AAC Blackout has become a go-to cartridge for short-range hunting and suppressed rifle builds, and it demands clean, consistent reloads. This die gives you the tools to produce them.
| Caliber | .300 AAC Blackout |
| Type | Bushing Full Length Sizing Die |
| Press Compatibility | Standard 7/8" reloading press |
| Material | Heat-treated steel, hardened to L.E. Wilson specifications |
| Neck Sizing Depth | Leaves 3/16" at bottom of case neck unsized |
| Lock Nut Height | .270" |
| Lock Nut Width (OD) | 1.250" |
| Lock Nut Thickness | .225" (inside to outermost edge) |
| Included | Adjustable depth decapping rod, extra decapping punch |
| Bushings | Sold separately; L.E. Wilson and Redding bushings compatible |
This is a standard 7/8" reloading die, so it works with any press that accepts full-length sizing dies in that size—which includes nearly every popular single-stage and progressive press on the market.
Yes, neck bushings are sold separately. L.E. Wilson manufactures bushings specifically sized for this die, and Redding bushings will also fit if you prefer those. You'll choose the bushing size based on your desired neck tension.
Sizing the entire neck can work-harden the brass, which reduces case life and can hurt accuracy. By leaving the bottom portion unsized, you minimize that work-hardening while still controlling the upper neck tension where it matters most for bullet seating and concentricity.
The die comes with an adjustable depth decapping rod and an extra decapping punch so you have a backup and can keep reloading without interruption if you need to swap one out.
