Precise performance from your ammunition starts with uniformity and achieving that consistency requires a measuring device you can trust. The Forster exclusive Co-Ax Case & Cartridge Inspector is engineered to ensure the highest level of accuracy by measuring three essential dimensions: neck wall thickness, case neck concentricity and bullet runout. With measurements precise to one-thousandth of an inch, this tool delivers exceptional accuracy to meet the demands of precision shooting and reloading. Unlike standard measuring tools, the Inspector uniquely evaluates both bullet and case alignment relative to the centerline axis of the entire cartridge or case, providing unmatched insights into uniformity. This innovative design ensures your ammunition is as consistent as your aim.
