The Forster Products Full Length Sizing Die for 300 Blackout (Model 005545) is built for reloaders who demand consistency and reliability every single time they load a round. This is a full length sizing die engineered to help you produce concentric ammunition that feeds smoothly and shoots true. Whether you're handloading for a subsonic 300 Blackout build, a precision rifle, or a hunting setup, a quality sizing die is non-negotiable—and Forster's reputation in the reloading community speaks for itself.
What sets Forster apart is obsessive attention to detail in manufacturing. Each die is machined from premium steel to exacting tolerances, then hand polished before and after heat treatment to deliver a finish that reduces friction and improves longevity. The die ships with Forster's signature Cross Bolt Die Locking Ring, which clamps the split ring at both ends rather than threading directly into the die itself—a design that increases rigidity and repeatability without risking thread damage over thousands of loadings.
The included E-Z Out Expander button is positioned high in the neck area to support and stabilize the case axis during the neck expanding stroke. This geometry keeps the case neck aligned and concentric as it's withdrawn from the die, translating directly to better concentricity in your finished rounds and tighter velocity spreads downrange. For 300 Blackout reloaders building subsonic loads or working up precision loads, that consistency matters.

| Cartridge | 300 Blackout |

| Included Components | Die, E-Z Out Expander button, Cross Bolt Die Locking Ring |
This is a full length sizing die specifically for the 300 Blackout cartridge, sized to Model 005545 specifications.
The die includes the sizing die itself, the E-Z Out Expander button, and the Forster Cross Bolt Die Locking Ring.
The E-Z Out Expander button is positioned higher in the neck area than most other designs. This placement supports and stabilizes the case neck and axis during the expanding stroke, keeping the case concentric as it's withdrawn from the die. Better concentricity leads to more consistent velocity and accuracy downrange.
Forster full length sizing dies are standard die format and compatible with most single-stage and progressive reloading presses, but we recommend verifying compatibility with your specific press before ordering. Contact us if you have questions about your particular setup.
