Best group of the day at 260 yards

I clad my target in sheet steel and painted it today. This is the best of three groups.

Harry states that we really should only take 4 out of 5 because of the inherent instability of the diablo pellet at long range.

If that was so, this would be a 4 shot group of 5 inches, as it is it is a 5 shot group of 8.5 inches at 260 yards.

Unfortunately the problem here was I adjusted for windage after the first shot.
