I didn't have anybody to screw with ..... at least not intentionally. My shots kept moving to the right -- adjust ---- the same, more to the right -- adjust -- the same, more to the right --- adjust --- nothing on the target at all. That's when it finally dawned on me that something other than my eye went seriously south. I didn't think of it at the time, but my target wasn't terribly far away from a gentleman to my right that was being very serious about sighting in his rifle (22 target). I hope I didn't give him a flyer off on the left side of his target to contemplate.
