Redding Instant Indicator/223 Remington

The Redding Instant Indicator for .223 Remington is a precision headspace and seating depth gauge built for reloaders who demand consistency in their ammunition. Whether you're sorting bullets for uniformity, checking case headspace, or verifying seating depth, this tool gives you repeatable measurements to within .001" — the kind of precision that translates to tighter groups and more reliable handloads. It's especially useful if you're combining cases fired in multiple rifles or working with sized brass that needs verification before loading.

The Instant Indicator approach cuts through the guesswork in setup and quality control. Instead of relying on feel or approximation, you can physically compare your loaded rounds, fired cases, and sized brass side by side. This is invaluable for sorting mixed brass, confirming your die adjustments are correct, and catching cases that need trimming before they cause problems at the press. The tool arrives with everything you need: a bore diameter bushing, surface contactor, shoulder contactor, headspace gauge, and full instructions.

Because the Instant Indicator works on cartridges within the same shoulder angle family, it offers flexibility beyond .223 alone — useful if you ever handload multiple calibers. Redding's reputation for manufacturing precision reloading tools means this gauge will hold its accuracy through hundreds of rounds of ammunition development and quality checks.
