Forster Neck Tension Gage - NTG-243

The Forster Neck Tension Gage (NTG-243) is a precision inspection tool designed for reloaders who prioritize consistency in ammunition assembly. Specifically engineered for the .243 Winchester caliber, this gage helps screen and sort brass before bullet seating to establish optimal neck tension parameters.

Accurate neck tension is crucial as it directly influences bullet release velocity and minimizes shot-to-shot velocity variation. The NTG-243 measures the inside neck diameter after case sizing and before bullet seating, allowing reloaders to identify which cartridges meet acceptable tension ranges. This step addresses the common issue of variable neck fit, ensuring that some rounds do not release bullets too freely while others do not grip too tightly.

Precision reloaders, competitive shooters, and hunters preparing match-grade or hunting ammunition will find significant benefits from the Forster Neck Tension Gage. Benchrest competitors and those aiming for sub-MOA accuracy recognize that the quality of case preparation, including neck tension uniformity, is essential for achieving tight group sizes.
