Protect yourself and your firearms

To achieve the highest degree of safety and accuracy, Lyman recommends that all bottleneck rifle cases be inspected after resizing to ensure that the proper headspace dimension is maintained. The best way to check this critical dimension is with a Lyman case length/headspace gauge. The reloader simply inserts the case into the gauge to insure that it does not exceed the maximum or fall below the minimum allowable headspace. In addition, the gauge will identify a case which exceeds the maximum allowable case length. Caution: Any case found with excessive headspace should be destroyed immediately.

Ensure proper case dimensions for safety & reliability

Lyman maximum cartridge gauges check all critical dimensions of pistol ammunition to insure proper functioning. These precision made gauges allow the reloader to check the case length, diameter and overall cartridge length of pistol ammunition. This inspection is considered mandatory by top competitive shooters who demand 100% reliability for
their competition ammo.
