The L.E. Wilson Adjustable Case Gage for 7mm Rem Mag (brand part no. CGA-7RMM) from L.E. Wilson is a two-piece cylinder-type gauge that measures case length from the base of the cartridge to the shoulder, as well as maximum overall case length. It lets a 7mm Rem Mag reloader check fired and resized brass for cone-to-head and overall length against the minimum and maximum SAAMI specifications, confirming ammunition is being produced within industry tolerances. The adjustable design makes it more versatile at the bench than a fixed one-piece gage for reloaders who want that base-to-shoulder reading.
