Lyman™ 243 Winchester Case Length Headspace Gauge

The Lyman Case Length Headspace Gauge is perfect for reloaders looking to achieve the highest degree of safety and accuracy. Lyman recommends that all cases be inspected after resizing to ensure that the proper headspace dimension is maintained.

Simply insert the case into the gauge to check that it does not exceed the maximum or fall below the minimum allowable headspace. If the case exceed the maximum allowable case length the case mouth will exceed the length of the gauge.

  1. This case gage works ... review by John on 6/21/2017

    This case gage works great. I load .243 for some of my family and this gage let\'s me know if the brass has been sized and trimmed to the correct demotions.

  2. awesome gage must have for reloader review by glenn on 6/21/2017

    For reloader this saves a lot of guessing about case resizing, and can be used to check overall case length, nice double check of reloaded ammo.

  3. Great addition to reloading tools review by Mike Mehren on 6/21/2017

    Simple quick way to detrrmine if your ammo
    Will fit in chamber properly
