Forster Products Inc NTG257 Neck Tension Gauge Red 257 Roberts Rifle Firearm

Overview

The Forster Neck Tension Gage (NTG) is a precision inspection tool used to screen and sort batches of brass before bullet seating. Consisting of four stepped diameters that increase in size up to the handle—with each dimension etched directly onto the metal tool—it allows reloaders to determine optimal inside neck diameters and check for internal "donuts" at the neck-shoulder junction. By inserting the stepped end into sized case necks until a slip fit is achieved, users can gather the precise measurements needed to ensure consistent bullet release and fine-tune their case preparation.
