Redding Instant Indicator/308 Winchester

The Redding Instant Indicator for 308 Winchester is a precision headspace and ammunition measurement tool designed for reloaders who demand consistency. Whether you're developing loads for competition, hunting, or precision rifle work, this gauge lets you quickly verify critical dimensions within .001" — tight enough to catch the variations that separate mediocre loads from truly accurate ones. It's built around a dial indicator system that makes comparative measurement fast and intuitive, so you can sort and verify ammunition at the workbench without guesswork.

What sets the Instant Indicator apart is its versatility. A single tool handles multiple tasks: comparing headspace between cases fired in different rifles, checking bullet seating depth uniformity across a batch, verifying shoulder bump consistency, monitoring trim length, and sorting loaded ammunition for consistency. You can also use it to set up your sizing die correctly by comparing sized cases directly to fired cases. This kind of quality control catches problems before they hit the range — cases that need trimming, bullets seated inconsistently, or excessive headspace that could affect accuracy or pressure.

The gauge comes equipped with interchangeable contactors (bore diameter and shoulder) plus a headspace gauge, giving you the flexibility to measure different aspects of your reloading process. If you're serious about ammunition uniformity — whether you're loading for a match rifle, a hunting rifle where every shot counts, or simply want to understand what your press is actually producing — this tool pays for itself in the confidence and consistency it delivers.
