If an MOA is (roughly) 1 inch at 100 yds and 2 inches at 200 yds ect. is saying "I shot 1 MOA at 100 yds the same as saying I shot 1 MOA at 1000 yds or 10". Put another way can I pat myself on the back the same at 100 yds as I woud at 400 yds or 800 yds if I shot a 1 MOA at any distance? Or is hitting 1 MOA at 1000 yds 10 times or a hunded times harder than hitting 1 MOA at say 300 or 600 yds? Is there a guide to what is considered a good shot at each distance? I have read several times a statement such as "I shot a sub MOA at long range". Many times they do not give the distance. Without the distance would the statement mean anything? Second question, when measuring an MOA I have read (though not from what I consider a reliable source) that you measure to the center of the two bullets furthest away from each other. Is this correct?
