Title: Math ? on MOA
Post by: Crunchy on April 22, 2019, 08:55:50 PM: Ok math isnt my strong point and my 17 year old isnt around to ask.

So Shooting groups at 200 yards. Outside spread is 1.41 from that I subtract .284 for bullet diameter which leaves 1.126. How does that number then equate to MOA. I know it is somewhere over .6 MOA but help me figure the math so I can do the rest of my groups.

1.126 divided by 2 divided by 1.047.

One is to scale the distance, the other is to convert the angle to a length
