The measurements I gave were after subtracting bullet diameter.
To convert that to MOA. At 200 yards. You divide the group size in inches by the number of inches in 1 MOA at that distance. I believe that 1 MOA is 1.047 at 100 yards so 200 yards 1 MOA is 2.094. Divide 1.311 by 2.094 to get .626 MOA.
The 300 yard group measuring 2.025 inches after subtracting bullet diameter. Use the same process as before. 1.047 inches is 1 MOA at 100 yards so multiply that by 3 for 300 yards. Which equals 3.141. so divide the group size in inches by the size of 1 MOA in inches at 300 yards. 2.025 divided by 3.141 equals .644 MOA.
