The Neck Tension Gage (NTG) is an essential inspection tool for reloaders, designed to quickly and accurately screen and sort batches of brass prior to the bullet seating process. By providing precise neck tension measurements, the NTG empowers reloaders to achieve exacting consistency and optimal performance during bullet seating. Comes in five calibers, this tool features four stepped diameters that increase incrementally up the shaft, with each diameter clearly etched onto the metal tool for easy reference. 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 enables fine-tuning of your case preparation, ensuring consistent neck tensions and improved accuracy. The NTG Neck Tension Gage is a reliable and user-friendly tool for achieving precision in your reloading process.
