[QUOTE="BountyHunter, post: 1841415, member: 12"] Look everyone, it is most important to understand that we are dealing with many variables to include lawyers from companies that are concerned about liability not accuracy. Too many people do not understand that, read the simple die instructions and take it as gospel as the best way to adjust dies for precision. Cam over will get you back to factory specs no questions 99.9% of the time. Though it is not uncommon to run into a die that is a shade too long and needs .015-.020 taken off the bottom. However, for precision, controlled headspace and case life you need to very accurately measure headspace and adjust your die down accordingly, not up. Hard to measure how much up you need to go. If you back the die off and have to come down to cam over, no harm no foul. However, if you automatically go to cam over and do not really understand and measure your headspace then you run into issues. That is exactly why IMO the top two die mftrs (Whidden and Redding) tell you to do it that way. Another reason to always measure every shellholder for height. I buy shellholders and put them in each die box and ONLY use that shell holder with that die set. That way my settings and measurements never can change. IF you have two guns of the same caliber, use mentioned Skip Otto Die Shims ($15) are your friend. Set your dies up for the shortest case and then add shims for the longer case.
