Please take Jeff's advice and only use the OAL gage from hornady that measures the base to the ogive of the bullet. This is the only true meaningful measurement that you can use with repeatable performance. This has to be done with every bullet brand, design, and weight. I also do it with every lot change just to ensure lot to lot variances are accounted for.
