[QUOTE="Mikecr, post: 2431776, member: 1521"] COAL is simply measured with calipers. A 'cartridge' is assembled ammunition. It's best to test for most accurate Cartridge Overall Length (COAL), or better still Cartridge Base to Ogive (CBTO) (which you would use a comparator for). You log this and reproduce it with the same local measuring tools and dies. The only way to know that each loaded cartridge is at same CBTO is to measure each during reloading. It's not a set-n-forget item. [/QUOTE]
