K80,
The instructions say counter clockwise to spead them and clockwise to move them closer together. If you look down the barrels as you do it you can see the barrels move. It works like a charm. I've been working on the 7x65R barrels. 1/4 turn counter clockwise and my troubles were solved with regard to crossing. Now at 100 yards they are side by side. What I have is the right barrel shooting higher than the left by 1.5" at 100 yards. I'm hoping to fool around with that by changing loads. But, if it can't be moved vertically so be it. It's good enough for me. By the way the gun was regulated with open sights and it now has a scope on it. The reregulating was really easy.
