Gehmann 138 .22 Rim Thickness Gauge




  • Measures .22 lr rounds
  • Rounds are placed in a hole and the gauge moved until it stops
  • Once gauged the round is placed with others of the same mark
  • Once batched, rounds have identical head-space and therefore be held in the breech in an identical position prior to firing - immediately improving each batches' ballistic consistency
  • This critical process is necessary to improve scores by paying greater attention to the smallest detail - sometimes a simple rule even forgotten by the best
