Redding Instant Indicator Headspace and Bullet Comparator With Dial Indicator 300 PRC

The Redding Instant Indicator Headspace and Bullet Comparator is a precision tool used by reloaders to measure headspace and bullet seating depth to the lands. It comes in two versions:

With Dial Indicator:

• Includes a precision dial indicator (usually 0.001" increments).
• Ready to use out of the box.
• Allows you to read measurements immediately—ideal for reloaders who don't already have a compatible dial indicator.
• Typically slightly more expensive due to the included dial.

Without Dial Indicator:

• Does not include the dial indicator – only the base tool insert(s) and stem(s).
• You must supply your own dial indicator (must be compatible – typically a 0.375" stem diameter).
• More cost-effective if you already own a dial indicator.
