[QUOTE="LaHunter, post: 1451170, member: 54963"] The variance comes when you base your measurement from the bullet tip. Cartridge Base To Ogive (CBTO) is the useful measurement when working on seating depth. Trimming your brass has nothing to do with either measurement, OAL or CBTO. The tip of the bullet is not making contact with your barrel, the bearing surface of the bullet is. The ogive reference point of the bullet is near the bearing surface. Since you are new, I would suggest getting some manuals. [/QUOTE]
