[QUOTE="BountyHunter, post: 537428, member: 12"] this works but two significant issues here the way it was explained. 1. this method does not measure where it touches. it measures the "jam" into the lands which is about .-040-.050 into the lands. does not it is a bad technique, you just need to remember where you are actually starting from, which is way into the lands. 2. You need a comparator to measure the ogive of the loaded bullet, and not the cartridge OAL. That can vary as much as .017 between bullets in the same box depending on that particular lot. there are several technical articles on the reloading part of sinclair internationals website, giving very detailed instructions using several tools that they sell that work quite well.
