F2S talks about "accuracy"

What is 1 MOA?
In the simplest terms possible, 1 Minute of Angle (MOA) is 1.047" at 100 yards, measured from the end of the muzzle.This distance increases in direct proportion to distance: 2.094" at 200 yards, 10.47" at 1,000 yards, 3.42" at 327 yards, etc.We, being lazy, tend to round this number to 1" per every 100 yards of distance. Frankly, it doesn't matter a whole lot, but it does let the guy that shoots a 1" group at 100 truthfully say that he shot a sub-MOA group, which makes people feel good about themselves.If you want to know more about Minute of Angle (Minute of Arc, semi-technically), the world of Google is a click away.Be warned: it's super boring, and won't help you shoot any better.
