Which group to choose?

So I am testing 50gr Zmax in my AR15 chambered in .223 Wylde. I already gone through OAL and now I am testing the powder charge.

Each powder charge is 5 rounds shot at 4 different times.

So my question is which group would you go with?

21.5 has the lowest MOA
22.0 is the most consistent

Attachment 520

I'd do each tenth between 21.5 to 22. You might find the best of both.

Never thought of it. I got some tunnel vision after so many trials / groups. Thanks

No problem.
