So data can sometimes show you the truth and other times drive you insane. I measured every piece of 100 that I sized in preparation for bullets heading my way. My chamber is 1.460 when measured to datum. I sized cases that were range pickups and were all rp aka Remington. This is for a bolt rifle so my criteria was 1.460 or less. The kings portion of cases sized 1.4595. I don't believe the .0005 but it's a 5 or zero on the digital I was using. Another large group was 1.460 and 8 pieces were rejected because they were not sufficiently sized. I could use them due to camming action but I don't want to. I had 3 that were below by 5 thousandths and I believe they never fully fire formed. Unfiltered I saw about .010 variation, but I only loaded 1.460 and below. What type of variations do you see. I'm sure I'm fighting an uphill battle not annealing but I'm data collecting, and that will be in the tests after I get some unannealed results.
