Redding Instant Indicator W/ Dial/308 Winchester

The Redding Instant Indicator for .308 Winchester is a precision headspace and seating depth gauge designed for reloaders who demand consistency. If you're building match-grade ammunition or simply want to verify your handloads are uniform from round to round, this tool lets you measure and compare critical dimensions to within .001 inch—far faster than adjusting dies by trial and error or relying on feel alone.

Reloading requires repeatability. Chamber pressure, accuracy, and case longevity all depend on getting seating depth, headspace, and shoulder bump right. The Instant Indicator turns what would be tedious tweaking into a straightforward visual reference. Mount it on your press, dial in your dies with confidence, then verify each loaded round matches your baseline. You'll catch dimensional drift before it becomes a problem.

The tool comes equipped with a dial indicator, bore diameter bushing, surface contactor, shoulder contactor, and headspace gauge—everything needed to sort bullets, compare sized and fired cases, check trim length, evaluate shoulder bump, and confirm loaded ammunition uniformity. Whether you're a precision rifle competitor, a serious hunter, or someone who simply respects their brass, this gauge transforms guesswork into data.
