Stick the dowel in the  barrel with the bolt in and record the distance the dowel protrudes. Shove the selected bullet in the barrel and hold it against the lands and measure the dowel protrusion. Subtract the first from the second measurement and that is your OAL to the lands. I just zero my caliper on the first and then read the oal directly as the second measurement. Then you can place that same bullet in a case to the depth you want and measure with a comparator to get the COAL and actual distance off the lands by repeating the process with the same bullet.</blockquote>
