The Neck Tension Gage (NTG) is a precision tool designed to quickly and accurately inspect and sort batches of brass before bullet seating. This essential tool provides reloaders with the critical information needed to achieve consistent and precise neck tensions, ensuring optimal accuracy during the bullet seating process. Comes in five calibers, the NTG features four stepped diameters that progressively increase in size toward the handle. Each diameter is clearly etched onto the metal tool for easy identification. To use, insert the stepped end into the neck of your sized case and slide it in until one diameter achieves a snug slip fit. The resulting measurement allows you to fine-tune your case preparation, ensuring uniform neck tension and improved performance. The NTG is a reliable and easy-to-use inspection tool for reloaders dedicated to precision and consistency.
