The Forster Products full length sizing die for 300 Win Mag is built for reloaders who demand consistency shot after shot. If you're working with bottleneck magnum brass and need a sizing die that prioritizes case concentricity and neck alignment, Forster's engineering cuts through the compromises. Unlike generic sizing dies, this one combines precision manufacturing with thoughtful design features that handle the reloading demands of a powerful magnum cartridge.
What sets Forster apart is the attention to the details that actually matter. Each die is machined from quality steel to tight tolerances, then hand polished before and after heat treatment—not for show, but because a smooth, consistent bore in your die translates to more uniform case sizing. The Forster Cross Bolt Die Locking Ring tightens both ends of the split ring rather than threading a screw directly into the die body itself, reducing stress on the die and improving longevity. For reloaders working with 300 Win Mag brass, the consistency of Forster dies means less sorting, better velocity spreads, and tighter groups downrange.
The E-Z Out Expander button on this full length die sits higher in the neck area than conventional designs, keeping the case neck supported and centered while the brass is withdrawn. This positioning maintains axis alignment during the critical neck expansion phase—especially important with magnum cases that benefit from uniform neck thickness. If you're loading for precision rifle work, elk hunting, or long-range competition, a die that preserves case geometry matters.

Forster dies are hand polished before and after heat treatment for a smoother bore, and the E-Z Out Expander button is positioned higher to better support the neck and maintain case alignment during expansion. The Cross Bolt Locking Ring also distributes clamping force across both ends of the split ring rather than relying on a single screw thread, improving die life.
This full length sizing die is designed for standard 300 Win Mag cartridges. As with any reloading die, it's important to verify compatibility with your specific brass and equipment before use.
Yes, the E-Z Out Expander button comes integrated with the die.
Forster full length sizing dies are compatible with standard reloading presses that accept standard die threads. Verify your press's compatibility before purchase.
