[QUOTE="PNWdude67, post: 2197257, member: 110615"] The most accurate and consistent method is “the Wheeler method” no tools needed other than a piece of brass bumped so there’s no friction on the shoulder in the chamber, your load press and seating die, and your stripped down bolt. Video on you tube search “Wheeler method of finding the lands” or something like that shows the process. Semper Fi. Also it really makes no difference if you do use the hornady cases vs a fired case from your gun. Base to Ogive abs COAL variability are not affected by what is happening between this to points of contact. Right? The Ogive contacting the lands and the base of the case contacting the bolt face are simply working as a caliper would if we had a way to get one in a chamber [/QUOTE]
