[QUOTE="barefooter56, post: 1102803, member: 85389"] Canadian Bushman, Do this test. Load up 5-10 rounds and purposely seat them so the run out on the bullet as measured up by the bullet/case mouth junction is over .005 run out. Load 5-10 rounds that are .005 run out or less. Check both groups all the way out to the tip of the bullet if you wish and record your findings of each group. make a trip to the range , make sure to fire enough fouling shots that the bullet strikes on the target are no longer rising but are clustering on the target. Now shoot each test group on separate targets. You can use flat base or boat tail bullets ( at 100 yards flat base would be best). Compare the group sizes and shapes. I did this on a whim just to see for myself. It was definitely an "ah ha" moment. [/QUOTE]
