Forster Products Neck Tension Gage Features The Forster Neck Tension Gage is used as an inspection tool to quickly and accurately screen or sort a batch of .277 caliber brass before the bullet seating operation. It consists of four stepped diameters that increase in size toward the handle with each diameter clearly etched onto the metal tool for easy reference. To use it the reloader simply inserts the stepped end into the neck of a sized case sliding it in until one of the diameters achieves a slip fit. The resulting value gives reloaders the information needed to fine tune neck tension for consistent bullet release during the seating process. This gage is used after case neck sizing and before bullet seating making it an important step in a thorough case preparation routine. It also allows inspection of the inside diameters of case necks helping identify whether a donut has formed at the neck shoulder junction that could affect seating consistency. At just 0.105 pounds the gage is compact enough to keep on a reloading bench without taking up significant space. Precision reloaders looking to improve consistency in their handloads will find this Forster Neck Tension Gage a practical addition to their process for sale at GrabAGun.
