These were the best two groups at about 21.7mm or .85" OD (appx. .63" CTC) but a couple others came close.
Good shooting but I am a little confused. Is this an entry or were you just testing loads? This challenge is deigned for the shooter to go out and fire two 10 shot groups and post the results. You post makes it sounds like you fired multiple 10 shot groups and just picked the two best for your entry.
From the rules: "Scoped rifles will fire two 10 shot groups at the target listed below (different targets are ok, just make sure both groups are on the same piece of paper)"
Ah I see. I did not follow the rules and am disqualified. I will have to try again another day...
I shot 10 rounds of each ammo I brought to the range after sighting it in. The groups I posted were of the two best performers. Then I shot much more
