Tally one piece rings and a Zeiss v4. I grouped the hits approximately 10 in right of point of aim. I fell multiple times on my rifle during this hunt and I'm somewhat making assumptions that I had lost zero. It's really hard to draw any hard conclusions though. At the time I just accepted re-zeroing my rifle as a normal thing. This was an out-of-state hunt and when I got there I checked and adjusted zero. I've since started zeroing off of much larger groups and have hardened my scope and mounting systems. All that to say it could very well be loss of zero, poor zero plus some undetected amount of wind or any combination of the above. As an aside. This rifle would require about 16 mph of wind to drift that much and I'm pretty confident I would have noticed that.Context? What setup lost zero?
