RE: Having Problem with sight picture When Bench Resting
I'd get your eyes checked just in case and yes you need to adjust your eyepiece to your shooting eye as well. I had the exact same problem happen 2 years ago and believe it was just fatigue. I found that I was really concentrating on the image or crosshairs to much, causing my eye to become fatigued and blurry. Just like you the more I tried the worst it got. I simply went back to the basics and when I felt this took a break, blinked or looked off, quit .. really anything to rest my shooting eye and calm down. Being I am severely left eye dominant but right handed it was suggested this also may be a culprit but it hasn't returned so thus I came to the conclusion of fatigue or triing to hard to hold on the target perfectly.
