Back at the range today, and there was some wind but with wind flags some of my doping was good.
The two best five shot groups at 100 yards measured .8 and .9 o-o.
It did not take much to get a flyer.
The intent today was to test Eley Match that was sorted for rim thickness.
They varied from .0005 to .002. Using the three dish rule would probably see the lows in one the highs in another with anything registering .0010 or .0015 going in the middle dish.
When I mixed up the various groups, it appeared there might be a slight difference. However, 3 or 4 from each group for a total of 14 rounds and one terrible flyer(1.6), 13 produced about a 1.08 o-o.
