As to accuracy, 20% of the 1k guns I am seeing at the present are 6.5 X 284. I have never seen a 6.5-06 in a 1k match. I am guessing there is probably a reason for that.
I would agree with the assessment of no 6.5 -06 in 1K matches. Of course I have an additional question? How many long actions do you see in 1K matches?The only one in the matches I have participated in is mine and I have done exceeding well... FWITW.... Stepping outside of the box is not always bad.
