I appreciate the thought T, I thought of that 2 and as a matter of fact it does make a significant difference with my ir defense unit. After scouring the in my opinion difficult instruction book I did not find any refrence but just to make sure all adjustments were made with same zoom.
Heres what convinced me mines broke. Before moving anything I wrote down the coordinates seen in the upper right corner, took a shot, moved one click took a shot, moved coordinates back to original setting and the poi had moved off the paper and off target almost 6 inches!!!
This is with a stag model 7 that with another day scope shoots sub moa and with the other ir unit that was mounted on it have seen lots of sub moa groups.
I'm not infalable but I have confidence in my handloads and my old eyes are experienced paper punchers.
Shipped it back today and will be sitting on pins and needles as I'm down to one scope now and the xp50 was my primary scanner. I just mounted the xp50 on the rifle as possible backup and to see how really possible it was to mount and dismount and remount and have same poi which surprised me was really good. After remounting the poi was only 3/4 inch off which in my opinion is not perfect but better than expected.
The people at Sellmark have been very good to deal with but tell me mines the first of this issue. The answer I got when I talked to support was disconcerting and Im not sure the individual knew or understood but he claimed that one click was supposed to move it .93 inches at 100 meters. I intend to try to reach this person and discuss more as he may have been reading from some spec sheet and transposed .093 to .93.
