The fliers must be the wind. Really.
Just for fun I fired 12 rounds from my single six, 50 yards, open sights, no adjustments. Except for the flier dead center of the X, I had a pretty good <6" group at 5 o'clock about 12" from the center. 10 of the 12 rounds were Blazer. Did almost as well with the single six and blazer as I did with the scoped rifles.
A similar 5 rounds from the Blackhawk .45 colt convinced me that I'm going to have to load differently for that range.
