"...Question for the op. In what order were the shots fired? I figure the first three were at poa and then they walked down due to recoil..."
Not sure, as I went through the cylinderfull single action in one continuous string without checking my impacts...standing offhand, two hand grip.
Recoil is negligible in this revolver, so I don't think it was a factor. More likely, it is the effect of my finding the black front sight on a black bull and lining it up with a silver rear sight notch in my preferred hold. I'm still learning this revolver.
My club has steel plates at 40 and 80yds...at 40yds, I was nailing the poodle sized ram plate easily. I was also hitting the bottom diamond on the spinners, so I went for the 80yd round plate, which is a foot wide. No problem hitting that, and I felt like Hickok45...I even said "life is good", LOL. I find shooting the plates helpful, as I can see the impact in the dirt on misses, and adjust my aim.
Here is a pic of our plates:
