Just rechecked my 200 yd zero before a longer range session. Found it about .8” low (group was .75” or .38 moa) so dialed up 2 clicks and put it in the case. Drove to my farm and set up at 535. Dialed in 8.6 moa and hit way high. Minus 2 clicks way high, minus two more still high, minus 2 more still high. Went for a 40 minute hike with 50# in the pack and carrying the rifle (Montana bound). Reverified 200 again now at plus 2.5”. Went down 5 clicks. Shot a 2 shot that was 1” low and 1.25” left. What? Plus two clicks up puts it back on center line but now 1/2” high. Had previously observed 5% over travel on tall target test and had suspected windage jump with elevation dial. Anybody seen this?
