Best I could measure without calipers.
Please help my range is 70 yards max and I want to be able to track my progress with MOA.

70 yard range with 1.75 inch shot spread is 2.3873 MOA

70 yard range with 1.5 inch shot spread is 2.0463 MOA

1 MOA = 1.047 inches at 100 yards.  This is usually close enough to just say 1 MOA = 1" per 100 yards.  

So 1.75 * 100 / 70 = 2.5 MOA.

nice shooting nonetheless.



the good news is your actually more  accurate than your measurements are giving you.

The correct way to measure moa on a target is to either measure to the outside edges of your two most distant shots AND THEN subtract the width of one of the rounds, or more simply do the same thing by measure to the center of the holes of your two most distant shots on your target.



nice hits.
