Shot the 223 tonight at 100, 150 and 200 to verify the balistics on my mil-dot chart. I shot 3 shot groups 10 minutes apart with a 3-5 mph wind at my back.
I came home and started looking at the numbers and I need a second opinion to verify my math.
Heres my results for the groups shot from bipods with a rear bag prone on the ground.
100 yards 0.552"
150 yards 0.617"
200 yards 0.733"
In theory I should have shot a 1.104" group at 200 yards, but its grouping smaller as I shoot further. (Typically this gun shoots in the .7-.8" at 200 yards.)
What is the proper way to determine the MOA of this load? Use the 100 yard group as MOA or divide the group size into the yardage and average the 3 distances?
