[QUOTE="LaHunter, post: 1275856, member: 54963"] Assuming you are not 'magazine limited', Cartridge Overall Length is not a very useful measurement for precision handloading. As you are finding, there can be a lot of variance in this measurement, and it really provides no useful info as long as you are not limited by overall cartridge length. The Cartridge Base To Ogive (CBTO) measurement is what you need to be measuring. This is a very useful and important measurement. With quality tools, a solid brass prep process, and high quality bullets you should be able to stay within +/- .002" in your CBTO measurement. Hornady makes a tool that you can use with your digital caliper to get this measurement. This is the measurement that you need to use when determining bullet seating depth. Good Luck [/QUOTE]
