These are the 2 terms used in describing the rifling found inside the barrel of a firearm.The word lands refers to the raised portion of the rifling,and the grooves refers to the lower portion of the rifling.By applying a hole micrometer you may determine the caliber of your firearm by measuring the distance between the 2 lands,and measuring the distance between 2 grooves.if you then compare the measurements you will find the true caliber of your firearm.
