The Redding 300 AAC Blackout full length sizing die is a core tool for reloaders who want to standardize and prepare fired .300 Blackout brass for the next loading cycle. This die sizes the entire cartridge—neck and body alike—restoring consistent dimensions across your brass so rounds feed reliably and perform predictably downrange. Whether you're loading subsonic or supersonic loads, a quality sizing die is where precision reloading begins.
Redding's full length sizing die includes a decapping assembly to remove spent primers and an expander ball to open the neck for bullet seating. The combination means you can move brass through the sizing step in one pass, saving time without sacrificing consistency. This is the workhorse die for hunters and precision shooters who load .300 Blackout for hunting, suppressed shooting, or precision rifle work.
Setup matters with sizing dies—we recommend using a headspace gauge to dial in the die's position on your press. A few minutes spent getting this right pays dividends in case life and chamber fit. Redding dies are known for solid construction and tight tolerances, and this full length sizing die is no exception.

A full length sizing die resizes the entire cartridge case—neck and body—to standard dimensions. This restores brass to a uniform state after firing, ensuring consistent feeding, chambering, and performance in your rifle. The decapping assembly removes the spent primer in the same operation.
The Redding 300 AAC Blackout full length sizing die comes with a decapping assembly and an expander ball. The expander ball opens the neck of the case to accept a bullet during the seating step.
We recommend using a headspace gauge when setting up this full length sizing die. Proper die setup ensures your brass is sized to the correct length and improves feeding and accuracy. A few minutes spent dialing in the die's position on your press will pay off in consistent reloads.
This is the individual full length sizing die. Redding also offers this die as part of full length die sets and deluxe die sets if you prefer a complete reloading package for .300 Blackout.
