It's a difficult question and hence why we are all debating this here.
Best to debate in a friendly way and trust that with this debate comes some additional reasoning about shooting so far at game animals and what the sport of fair chase hunting really means to all of us.
1.5 MOA 100% of the time...at 700 yards in a moderate wind? I'll take that bet. How much?
Please re-read what I did say. I have two rifles that shoot 0.563"-0.719" (sub-MOA) at 100 yards. At 700 yards, (never said moderate wind), without any gusts, I'm usually within about 7"-8.5". I do fire about 2,000 rounds downrange every year across various rifles so I practice much more often than the average hunter using a box of 20 to prepare for the season
