The Neck Tension Gage (NTG) stands as an essential tool for the discerning reloader, providing a swift and precise method to evaluate your brass before bullet seating. In the pursuit of accuracy, neck tension plays a pivotal role; this inspection tool offers reloaders critical insights needed to achieve consistent neck tensions during the bullet seating process.
After you have sized your case necks but before you seat bullets, deploy the NTG to ascertain optimal inside neck diameters. This ensures that each round releases its bullet consistently upon firing—an indispensable factor in precision shooting. The NTG also allows for meticulous inspection of case necks to detect any unwanted "donuts" at the junction of neck and shoulder which can interfere with performance.
Available across five calibers, this robust tool features four stepped diameters etched directly onto its metal shaft. These increments increase in size toward the handle. To use it, simply insert the stepped end into your sized case's neck until one diameter fits snugly without force—this is your slip fit measurement.
The resulting value from using this gage empowers you to fine-tune your preparation process with confidence and exactitude. For those committed to refining their craft, the Neck Tension Gage is not just a convenience; it's an instrument of precision.
