The Neck Tension Gage (NTG) is a practical and precise inspection tool designed to help reloaders quickly and accurately screen and sort batches of brass before bullet seating. By providing critical measurements, the NTG enables reloaders to achieve consistent and exacting neck tensions, ensuring superior accuracy during the bullet seating operation. Comes in five calibers, the NTG features four stepped diameters that progressively increase toward the handle. Each diameter is clearly etched on the tool for easy identification. To use, simply insert the stepped end into the neck of a sized case and slide it until a snug slip fit is achieved with one of the diameters. The measurement obtained guides fine-tuning of case preparation, ensuring uniform neck tension and enhanced reloading performance. Reliable and user-friendly, the NTG is an indispensable tool for reloaders committed to precision and consistency.
