Redding Instant Indicator, .280 Remington Improved 40

The Redding Instant Indicator, .280 Remington Improved 40 (Redding part no. 17428) is a headspace and bullet-seating-depth comparator built for .280 Remington Improved 40 brass. By swapping one or two internal parts, it lets a handloader compare the shoulder position of fired versus resized cases, check bullet seating depth uniformity, and sort brass fired in different rifles, all in a fraction of the time a caliper-based method takes. A separate dial indicator is required to read the comparator; the Range Adapter accessory can also be added for press-free use. It mounts in a press with the correct shellholder for .280 Remington Improved 40 and is a staple on precision reloading benches.
