Thanks for the additional thoughts.
I keep the gun on my shoulder when shooting single shots. Many times, however, since I am shooting the Sierra 77s, I shoot from the magazine. Maybe I should change that.
I hadn't considered the focus on the front sight idea.....though I have to think about it all the time when shooting Bullseye pistol.
It is the almost mirror like shift - of the good shots - from the right half of the target to the left half that is making me wonder because the only conscious change was one click left. Should have been about a half a ring.
