The Forster Products Datum Dial Body Assembly is the foundation of a precision reloading measurement system designed for handloaders who demand consistency and accuracy in case preparation. This is the core body unit—the mechanical backbone that lets you attach Forster's interchangeable Cartridge Dials to establish repeatable datum reference points on your cartridge cases. If you're serious about sorting brass by length, measuring case head space, or tracking dimensional changes across your handload batches, this assembly gives you the infrastructure to do it methodically.
The body assembly ships complete with all the mechanical components you need to get started: the main body, thumbscrew for securing dials, a ball detent for positive positioning, socket head cap screw, washer, and cup point set screw. Two hex keys are included so you can assemble and adjust without hunting for tools. Note that Cartridge Dials are sold separately—you'll choose the dial inserts that match your specific calibers once you have the body in hand.
This approach—a modular dial system built around a single, quality body—keeps costs down if you reload multiple calibers and need to swap dials frequently. It's a smart investment for the precision-focused handloader who wants a repeatable, caliber-flexible measurement platform without buying a whole new tool for each round you work with.
| Product | Datum Dial Body Assembly |
| Brand | Forster Products |
| Included Components | Body, thumbscrew, ball detent, socket head cap screw (6-32 x 1/2"), washer (.250 x .156 x .013), cup point set screw (6-32 x 1/4"), 7/64" hex key, 1/8" hex key |
| Cartridge Dials | Not included; sold separately |
Yes. The Datum Dial Body Assembly is the base unit only. You'll need to purchase the specific Cartridge Dials that match your reloading calibers to complete the system.
The body assembly itself is caliber-agnostic. Caliber compatibility is determined by which Cartridge Dials you purchase and attach to it. Forster makes dials for most common rifle and handgun cartridges.
The package includes two hex keys (7/64" and 1/8") that cover the assembly and adjustment tasks. No additional tools are required to get the body ready for use.
No. This is the body assembly only. To measure cartridge cases, you'll need to add the appropriate Cartridge Dial for your caliber. Once assembled, the complete system lets you establish repeatable datum points for precision case evaluation.
