Why play around with it. Find the group that shoots the tightest and if they cross adjust the barrels so they don't.
My 9.3x74R set of barrels crossed @ 100 yards very little mind you but they crossed. I found the load that shot the tightest. I turned the barrel adjusting screw 1/4 of a turn and voila! problem solved.
My 7x65R set of barrels shot lousy with all factory loads even after adjusting the barrels to keep them from crossing. We developed a load using a heavier bullet. The pattern tightened up considerably and I adjusted the barrels at 100 yards to where I wanted them to shoot.
