The Neck Tension Gage (NTG) is an essential inspection tool for precision-minded reloaders, allowing you to swiftly and accurately screen and sort brass before bullet seating. Designed with meticulous attention to detail, each NTG in this kit offers reloaders the critical measurements needed to create consistent neck tension for optimal bullet seating. The kit includes gauges for five popular calibers .224 Valkyrie, .243 Winchester, .264 Win Mag, .284 Winchester and .308 Win each crafted with four stepped diameters that gradually increase in size toward the handle. Each diameter is permanently etched on the tool, making it easy-to identify and use. By simply inserting the stepped end into your sized case neck until a slip fit is achieved, you gain precise feedback to fine-tune your case preparation process and ensure uniformity across your brass.
