Forster Bullet/Cartridge Dial #2 for 172, 204, 257, 277, & 338 Dia. Bullet

• Caliber-specific measurement support: This dial is made for .172, .204, .257, .277 and .338 caliber bullets, so it lets reloaders work with the bullet diameters they actually use instead of relying on a one-size-fits-all measuring surface.
• Designed for the Datum Dial system: Used with the Forster Datum Dial, it helps compare bullet and cartridge dimensions consistently, which is useful when setting up seating dies and tracking changes between loads.
• Quick interchangeability: As part of the Datum Dial concept, the dial format makes it easy to switch between supported calibers, saving bench time when loading for more than one cartridge family.
• Useful for repeatable handloading setup: Consistent comparative measurements help reduce guesswork during case preparation and ammunition setup, making it easier to return to a known seating or measurement baseline.
• Made in the USA: Forster builds this accessory in the United States, matching the brand’s long-standing focus on precision reloading and gunsmithing tools.

About the Datum Dial Series

The Forster Datum Dial series is built for reloaders who want a practical way to make repeatable comparative measurements during ammunition setup. Within Forster’s measuring-tool lineup, the system sits alongside the company’s other precision reloading tools and focuses on one of the most useful bench tasks: checking dimensional relationships on cases and loaded cartridges in a consistent way. Rather than treating every cartridge the same, the Datum Dial system uses interchangeable dials so the tool can be matched to specific case shoulders or bullet diameters.

This modular approach makes the series especially useful for reloaders working across several chamberings. The design philosophy is straightforward: keep the measuring process organized, caliber-specific and easy to repeat from one loading session to the next. In practice, that helps when comparing brass before and after sizing, checking loaded rounds, or returning to a proven die setting. The system is aimed at handloaders who value process control, whether they load for hunting ammunition, target shooting or general rifle use. Across the series, the emphasis is on bench efficiency, clear caliber matching and compatibility with the broader Datum Dial ammunition measurement system.

About the Forster Bullet/Cartridge Dial #2 for 172, 204, 257, 277, & 338 Dia. Bullet

The Forster Bullet/Cartridge Dial #2 is the caliber-specific part of the Datum Dial system intended for reloaders who work with .172, .204, .257, .277 and .338 diameter bullets. Its role is simple but important: it gives the measuring system the correct contact geometry for those bullet sizes, which improves consistency when comparing cartridges and setting up loading operations. For a handloader, that matters because repeatable measurements are what make die adjustments easier to understand and easier to duplicate later.

This dial is particularly useful on benches where more than one rifle caliber is loaded. Instead of improvising around unsupported bullet diameters, the correct dial keeps the process organized and helps maintain a more consistent reference point from one cartridge to the next. That is valuable when checking loaded ammunition during setup, refining seating adjustments, or documenting a preferred load configuration for future batches. Because it is part of the Datum Dial platform, it also fits naturally into a workflow built around comparative measurement rather than rough estimation.

Physically, this is a compact accessory at 60.00 g, so it adds capability without taking up much bench space. As a USA-made Forster accessory for case-preparation and measurement work, it suits reloaders who want a dedicated tool component for supported bullet diameters rather than a compromise solution.

About Forster

Forster Products dates its history to 1935 and has long focused on precision reloading and gunsmithing tools. The company is based in Lanark, Illinois and states that its products are made in the United States. Across its catalog, Forster is known for practical bench equipment such as reloading dies, case trimmers, headspace gauges and sight-mounting fixtures, all aimed at shooters and reloaders who value repeatable mechanical setup.

Among its better-known products is the Co-Ax Press, and the company’s die range also includes designs such as Bench Rest Seater Dies, which use a close-fitting chamber to help align the case and bullet during seating. That emphasis on alignment, measurement and controlled adjustment carries directly into Forster’s comparator and inspection tools, including accessories for the Datum Dial system.
