Wilson - Ajustable Case Gauge - 338 Winchester Magnum

For belted mags. 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. These gages, which can be adjusted to be used with individual rifles of the same caliber, will enable the handloader to control the amount of resizing simply by measuring a fired case. Overall length can also be checked with these gages.
