The reason I'm confident is because of the "other" 3 shot groups, albeit all with different loads. From 42.5 to 43.1 represents 12 shots, all of which were 6 or less and 3 of which were 5 or less. We'll see. I welcome your skepticism. I agree the proof is in the pudding and I'll be testing a new scope and distances out to 300 yds this weekend. I will post the results good or bad.
