Did a box test with my .30-06 today. The target is in inches, but scope is in mils. POA was center of bottom left target. Firing sequence was: POA > 2 mils (20 clicks) Right > 2 mils Up > 2 mils Left > 2 mils Down. One round fired after each adjustment. Did this for 3 "laps" for a total of 13 rounds fired. Scope seems to have done well. The groups are spaced almost exactly 7.2" apart. It certainly is repeatable. I'm going to run it again at some point and see how it does (and I do) under different conditions. So far so good I think, but I am a bit concerned that the upper right group is a tiny bit lower than it should be.
The middle group is 10 rounds fired from the same rifle. All of this was done off a bipod with rear support bags.
