So if I use bullet A to find max COL when the ogive touches the lands, then do I use this same COL @ the ogive for bullets B and C? Or do I have to retake this measurement for each bullet?</div></div>
Retake it for each bullet. The problems that can be encountered can be give you over pressure. The only way that would work is if you had a true chamber gauge that was cut with the same ream used on the barrel. It really isn't that big a deal to do for each bullet profile.
