Just to piggyback on this.. I know the IR hunter MKII will adjust different amounts based on how much digital zoom is set. I don't remember specifically but I think it's like 1.3 inches at 100yds per click with native zoom and at 4x digital each click is only like 1/3 of an inch adjustment at 100. I could be way off on those specific click values so don't quote that but I remember figuring that out one day at the range and then reading it later specifically in the manual.50 yds zero works great for me - makes for no hold over on shots out to 200 (120SST out of 12.5" 6.8)
I'm not sure I could reliably zero my Zeus 640 past 100 if its a 2 MOA sight. Wouldn't it be akin to zeroing a low power optical scope at a distance where the thickness of the reticle obscures 3-4" of the bullseye?
I have 14.5" 6.8 shooting 120grain hornady sst
My shots at as far as I can take them. I hunt flat and hilly pasture but we are talking you can see 1500 yds. So 0-300 would be my shots just bc much further the thermal can't see good. I never heard of a 50 yd zero to this forum that's why I'm asking. I have zeroed my rifles my whole life 1"-2" high at a 100. So I never thought 50 yd made sense until y'all saying 1.5 low at 200 why not just zero for 200? Would it be way off if you shot at 50?
