Redding Instant Indicator Headspace and Bullet Comparator With Dial Indicator 6.5 PRC

The Redding Instant Indicator Headspace and Bullet Comparator for 6.5 PRC is a precision measurement tool built for reloaders who demand consistency in their handloads. Whether you're fine-tuning shoulder setback after resizing, tracking case length growth, or dialing in bullet seating depth for group-tightening accuracy, this dial indicator tool gives you the real-time feedback needed to catch variables before they become errors downrange. It's the kind of benchrest-grade quality control that separates deliberate handloading from guesswork.

Designed specifically for 6.5 PRC brass, the Instant Indicator comes pre-mounted with a dial indicator and a 6.5 PRC-specific case insert, so you're measuring against the true datum line on your case shoulder—not eyeballing it. Drop a fired and resized case into the gauge body and instantly see how much you've bumped the shoulder back. Use it after seating to verify overall length from shot to shot. Track which brass in your batch has grown past safe limits and needs trimming. For long-range shooters and precision reloaders, these small, repeatable measurements are the difference between a load that performs and one that doesn't.

The tool arrives fully assembled and ready to use: dial indicator installed, case insert fitted, and instructions included. If you're working up loads for 6.5 PRC or sorting and processing brass with real precision, this is a straightforward way to measure what matters and document it as you go.

Specifications

Frequently Asked Questions

What exactly does the Instant Indicator measure?

It measures headspace from the datum line on your case shoulder (to verify how much you've bumped it back during resizing), case length to the shoulder, overall cartridge length (OAL), and base-to-ogive bullet seating depth. Each measurement helps you maintain consistency and safety in your reloads.

Is this tool specific to 6.5 PRC only?

Yes. The Instant Indicator comes with a 6.5 PRC-specific case insert and is designed to measure against the correct datum line for 6.5 PRC brass. It is not compatible with other cartridges.

What comes in the box?

The package includes the Instant Indicator tool body, a pre-mounted dial indicator, a 6.5 PRC-specific case insert, and instructions. The dial indicator is ready to use out of the box.

Who should use this tool?

Long-range shooters, precision reloaders, and benchrest competitors who need to verify shoulder setback, track brass dimensions, and ensure consistent bullet seating depth for accuracy. It's also useful for anyone sorting and processing brass and wanting to document critical measurements.
