Forster Products Datum Dial Body

The Forster Products Datum Dial Body Only (brand part no. DD1010) is the base dial-indicator unit for the Forster Products case and bullet measurement system, built for reloaders who already own compatible inserts and need a replacement or second dial body. It reads case shoulder datum (headspace) and bullet seating depth so handloads can be tracked and repeated consistently from batch to batch.

Key Specifications

• Reads case shoulder datum (headspace) and bullet seating depth for consistency checks.
• Sold as the dial body only; caliber-specific inserts are purchased separately.
• Compatible with the Forster Products Datum Dial insert lineup for cross-caliber use on one dial body.
• Gives repeatable readings for tracking sizing and seating consistency across a loading session.

Frequently Asked Questions

Do I need inserts to use this? Yes, caliber-specific inserts are required to measure a given cartridge; the body only reads what the insert presents to it.

What does this tool actually measure? It measures case shoulder datum (a headspace reference point) and bullet seating depth relative to the shoulder, both key numbers for consistent handloads.

Is this a go/no-go gauge? No, it’s a comparative measuring tool that gives a numeric readout rather than a simple pass/fail check.
