Question: what does 2 moa mean?
Answer: You know that a MOA spreads out 1″ per 100 yards, so 1 MOA at 300 yards is 3″. Therefore, for your calculations at that 300 yard target, you should think in 3″ increments. By doing so, you can easily see that 2 MOA is just 2 of those 3″ increments, or 6″ total.
