Lyman recommends inspecting resized bottleneck rifle cases for precise headspace dimensions to guarantee the highest level of safety and accuracy. With Lyman's case length/headspace gauge, checking these critical measurements is quick and simple. The reloader can easily insert the case into the gauge to ensure it meets the required specifications, avoiding any cases that fall outside the allowable headspace range. The gauge also helps detect cases that are too long. If excessive headspace is found, dispose of the case immediately for safe reloading. Lyman's gauges eliminate guesswork and provide reloaders with the confidence needed for consistent, high-quality ammunition.
