mathman,
I wasn't questioning your math which I'm sure is spot on. But rather giving more context to the accuracy relative to the intended use. I know you get this, but while MOA subtension increases linearly as distance increases (1.04" at 100 yards, 2.08 at 200 yards, 3.12 at 300 yards etc). shot dispersion does not increase in a linear fashion as the distance increases. A rifle shooting 1" groups at 100 yards will very likely shoot bigger than 3" groups at 300 yards.
