I have a Leupold VXIII 6.5x20x40. I called and asked Tech. support if they could install MK 4 M1 turrets and a mil-dot reticle, they said yes. But then later I thought. If the line values of the M1 turrets are 1/4 MOA and 1/4 inch for the VXIII, I'm not sure the M1 MOA turrets will reflect the true "click value". Any Help? Thanks
