Forster Full Length Sizing Die 25 WSSM, Bench Rest

• Bench Rest full-length sizing: Sizes the entire case while also decapping in one operation, helping fired .25 WSSM brass chamber reliably again without adding extra setup steps.
• Steel die construction: A steel body gives the die the rigidity and wear resistance needed for repeatable sizing over long loading cycles, which matters when maintaining consistent case dimensions.
• Standard 7/8"-14 thread: Fits common reloading presses, so it integrates easily into an established bench setup without requiring proprietary adapters.
• Single-die format: This configuration suits reloaders who need a dedicated full-length sizer for a specific rifle cartridge, whether as a replacement die or as part of a custom die combination.
• .25 WSSM chambering: Built for the .25 WSSM / .25 Winchester Super Short Magnum, it supports precise case preparation for a short, high-performance rifle cartridge where dimensional consistency is important.

About the Bench Rest Series

Forster Bench Rest dies are built for reloaders who want precise cartridge alignment and repeatable results from a conventional press setup. Within the company’s die lineup, the Bench Rest series sits as a precision-focused option for shooters loading hunting ammunition, varmint rounds, and carefully tuned rifle loads where case uniformity and bullet alignment matter. The series is known for straightforward mechanical design, close manufacturing tolerances, and compatibility with standard reloading equipment rather than a proprietary system.

In practical use, the Bench Rest family is intended to simplify accurate ammunition assembly by keeping each stage controlled and consistent. Full-length sizing dies in the series prepare brass for dependable chambering after firing, while the matching seating dies in the broader Bench Rest range are designed around careful cartridge alignment during bullet seating. That makes the series a natural fit for reloaders who want a step up from basic dies without moving to a more specialized bushing or micrometer-based setup. Steel construction, standard press threading, and a focus on repeatable sizing and seating geometry define the series across many rifle chamberings.

About the Forster Full Length Sizing Die 25 WSSM, Bench Rest

The Forster Full Length Sizing Die 25 WSSM, Bench Rest is a dedicated rifle sizing die for reloaders working with .25 WSSM brass and needing reliable full-length resizing for repeat chambering. Because it combines decapping and full-length sizing in one die, it streamlines brass preparation and keeps the loading sequence efficient. That is especially useful with a short, high-intensity cartridge such as the .25 Winchester Super Short Magnum, where consistent case dimensions help support smooth feeding and predictable fit in the chamber.

This model uses a standard die design rather than a bushing system, making setup familiar for reloaders who prefer a conventional sizing workflow. The steel construction supports long service life and stable sizing characteristics, while the standard 7/8"-14 thread allows the die to fit widely used presses. As a single-die format, it works well for replacing an existing sizer, building a caliber-specific die arrangement, or pairing with a separate seating die chosen for a particular loading method.

For practical bench use, this die is aimed at shooters who want dependable case resizing without unnecessary complexity. Its bottle-neck rifle case geometry is tailored to the cartridge family it serves, and the Bench Rest designation reflects Forster’s emphasis on dimensional consistency. For hunting or precision-oriented handloads, that consistency matters because uniform brass preparation is one of the foundations of repeatable ammunition performance.

About Forster

Forster Products dates its history to 1935 and has long focused on tools for precision reloading and gunsmithing. Based in Lanark, Illinois, the company states that its products are made in the United States. Its catalog covers reloading dies, case trimmers, headspace gauges, and sight-mounting fixtures, giving it a strong presence among reloaders who value careful case preparation and repeatable setup.

One of the company’s best-known products is the Co-Ax Press, and Forster is also closely associated with its Bench Rest Seater Dies, which use a close-fitting chamber to help align the case and bullet during seating. That background is relevant here because the same design philosophy carries into the company’s sizing dies: practical mechanical precision, compatibility with serious bench use, and a focus on consistent ammunition assembly rather than unnecessary complication.
