So I dialed in 56 MOA and took two sighter shots in the dirt to foul the bore and get a wind reading, then moved over on the 24" square (12x24 each) steel.
First shot was the low/left hit, next was the low impact in the dirt just below it, 3rd was the upper right hit, 4th was just a RCH left of the steel (in the shadow), and 5th was the low right hit. I'm calling it around a 24" group. Not bad consider the head on blow.
Looking back.....
Set-up was at the back treeline in the gap three quarters of the way to the right by the tallest tree....
