I have an OLD leupold Vari-x III 3.5-10x40mm 1 inch tube that I put on my new 25-06. What I am thinking is if leupold will put a CDS dial on it maybe I can make is a 600 or so capable rifle. But how dependable are the clicks on those old things. its the old coin slot dial but when i look at the drocc hairs on the grid in my leupold bore sighter and turn them the crosshairs seem to move right. I realize I may want to dial past then back down when coming up in elevation since it has a single erector spring. Has anyone used one with a different turret at all? How did it work?
