Example, if a rifle shoots 1 MOA @ 100 yards, it does not mean it will shoot 10 MOA @1000 yards. I know this(or think i know it). But I can't explain fully why. The biggest variable I am assuming is wind, but what other variables come into play? Exclude the shooter from this discussion, i guess that actually is the biggest variable. Wind bullet powder amount powder burn consistency scope velocity What am I missing from the list?
