Forster 308 Neck Tension Gage

The Forster 308 Neck Tension Gage is designed to assist reloaders in achieving precise neck tension for consistent bullet seating. It is used after case neck sizing and before bullet seating to measure the inside diameter of cartridge case necks.

This tool helps identify if a "donut" has formed at the neck-shoulder junction, which can affect bullet release and accuracy. The gage features four stepped diameters etched on the metal, allowing users to find the optimal inside neck diameter by sliding the tool into the case neck until a slip fit is achieved.
