If I measure a slug from a barrel that has even lands and grooves the land and/or groove has the same on the opposite, so a micrometer can measure from a groove to a groove and a land to a land of the opposite side of the slug. The problem is with odd number l&gs one side of the mic is on the land while opposite side is a groove.
So is there an accurate way to measure the diameter of the bore when it has off rifling and I don't have a way to measure the depth of the groove?
