The Neck Tension Gage (NTG) serves as an indispensable tool for the meticulous reloader, offering precision and efficiency in sorting batches of brass before bullet seating. This instrument is crafted to provide critical insights into neck tension, a key factor that influences the accuracy and consistency of your ammunition.
Post case neck sizing, but prior to bullet seating, the NTG allows you to determine the optimal inside neck diameter. By doing so, it ensures a consistent release of bullets from your reloaded rounds. A crucial feature of this gage is its ability to inspect for potential "donuts" that may form at the junction between the neck and shoulder—an occurrence that can severely affect performance if left unchecked.
Available across five calibers, this inspection tool comprises four stepped diameters etched on its durable metal body. Each step increases incrementally until reaching the handle—a design choice that facilitates ease-of-use while maintaining precise measurement capabilities.
The operation is straightforward: insert the stepped end into your sized case's neck and slide it gently until one diameter achieves a slip fit within the case neck. The identified value then guides you in refining your case preparation process further.
For those who demand excellence from their handloads, trusting each round fired will perform with unwavering reliability—the Neck Tension Gage stands ready as an ally in achieving superior ballistic results.
