I often wondered if I was just imagining this phenomenon. But I swear I can feel the rifle when it is in/out of tune.Great post. I will add that even with bad paper with poor backers, or wet paper, if you know what to look for, you can see the changes in the holes as tune changes.
When tuning, I normally see changes in the bullet holes as the gun goes in and out of tune. Of course, there are other things that I see as well, down to a change in the recoil/sound and feel of the ignition. Sort of hard to describe but they all go hand in hand.
