I was lucky in that the double I bought had three sets of barrels. The 7x65R came with a Ziess Diavari 1.5 - 6.0.
It's been fun shooting all of the barrels and changing from one to the other.
I'm just now honing in the accuracy of this particular set of barrels. It swings beautifully, it's light and fast on target. I hope to take it hunting soon for some ballistic reports on game animals.
