I myself just recently sent off and older VX III in 2.5x8 that was all goofed up in both elevation & windage adjustments. No spare parts anymore they said, sending me a new VX3 HD 2.8 with CDS as a replacement. I'm not a turret turner, but at one time I did play with one on a 4.5x14x40. I may as well put it on my Mesa 300WM. I have a new Burris FFII 3x9 on it now, so hey, Upgrade! I love Leupold, always have! smile
