The Neck Tension Gage (NTG) is a precision inspection tool that allows reloaders to quickly and accurately screen and sort brass before the bullet seating process. By measuring neck tension, the NTG provides vital information for achieving consistent and precise results during bullet seating, ultimately enhancing accuracy and performance. Designed for versatility, the NTG is available in five calibers and features a stepped design with four increasing diameters etched onto the metal tool for easy identification. To use, simply insert the stepped end into the neck of a sized case and slide it in until one of the diameters achieves a slip fit. The measured value offers reloaders a clear guide for fine-tuning case preparation, ensuring optimal neck tension. The NTG is an invaluable tool for reloaders seeking precision and uniformity in their reloading process.
