Redding Instant Indicator Headspace and Bullet Comparator With Dial Indicator 7mm PRC

The Redding Instant Indicator Headspace and Bullet Comparator with Dial Indicator for 7mm PRC gives reloaders a straightforward way to dial in precise headspace and bullet seating depth to the lands. This is one of the most critical measurements in hand-loading: get it wrong and you'll face feeding issues, case stretch, or dangerous pressure spikes. With the dial indicator already included, you're ready to measure right out of the box—no need to source a compatible indicator separately or futz with borrowed equipment at the bench.

If you're building ammunition for a 7mm PRC or fine-tuning loads for competition or long-range hunting, this tool takes the guesswork out of seating depth. Rather than relying on rough estimates or generic published data, you can measure where your bullets actually sit relative to the rifling in your specific chamber. That precision pays dividends in consistency, accuracy, and reliability across your handloads.

The included dial indicator reads in 0.001" increments, giving you the resolution you need to catch small variations. Once you've found your optimal seating depth, you can lock it in and replicate it with confidence on every round you produce. For serious reloaders who demand tight tolerances, this Redding comparator is a compact, no-nonsense addition to the loading bench.
