My rangefinder was not able to accurately display the range. So 6 shots later im on target. But aside from knowing this particular hunting spots range, im left with a big guess. I believe its more than 800 yards, less then 900. Im sighted in @100 with 1.4''scope height. 900ft alt, 85*. I dialed in 4.2 MOA or 22 clicks (this is right on for 500) but was way low. So, I eventually found my way to 107 clicks and managed 2 hits out of 3 shots (once I knew the elevation dial was correct) Any clue just how far the shot was? I would shoot, and lose focus and quickly readjust to my scope right as it impacted. (This was @the river, so my spotter had instant feedback of shot placement.) Thanks guys.
