You might want to look at Criterion and Shilen at Northland Shooters Supply. Jim is known to send out specs on the barrel contours. The specs he sent me were OD in one inch increments. All I had to do was specify which contour I was looking for. It also helped me determine weight.
And he is a sponsor of this site....
On Edit: I didn't realize you had already made the purchase. Sorry.
