L.E. Wilson Adjustable Wilson Case Length Headspace Gauge, 270 Weatherby Magnum
LE Wilson Case Length Headspace Gauges help to resolve the inherent problem of potentially over sizing your bottleneck rifle brass. And the most important use of a cartridge case gauge is for setting up 7⁄8"-14 press type full length resizing dies. Headspace of fired rifle cases can quickly and accurately be measured using this tool with a caliper.
For Belted Magnums. While the belt provides support for proper headspace, the life of the case will drastically shorten unless resizing is held to a minimum at the shoulder.
Suitable for: 270 Weatherby Magnum
