The Neck Tension Gage (NTG) is an essential inspection tool for any serious reloader. Designed to swiftly and accurately screen a batch of brass, this tool offers the precision needed before you seat your bullets. Understanding neck tension is critical; it ensures that each round performs with consistency and reliability.
Utilizing the NTG after case neck sizing but before bullet seating helps determine the optimal inside neck diameter. This process guarantees a consistent release of your projectiles from reloaded rounds, enhancing overall performance.
An additional feature of the NTG is its ability to inspect inside diameters at the junction where the neck meets the shoulder. This inspection ensures no "donut" has formed—an issue that can affect accuracy if left unchecked.
The NTG comes available in five calibers, catering to various needs. Its design includes four stepped diameters etched onto a metal handle, increasing incrementally until reaching said handle. To use, simply insert these steps into your sized case's neck until one diameter achieves a slip fit. Use this measurement as guidance for refining your case preparation approach.
Incorporate the Neck Tension Gage into your reloading routine for greater control over ammunition quality and performance—it’s an investment in precision every marksman will appreciate.
