I have that same 8.5-25 VX3i that I use on my "Any" rifle for NRA Long Range and Mid Range prone matches, mainly 600 and 1000 yards. It's a great scope. The adjustments are repeatable, and it holds zero extremely well. It gets taken on and off and swapped with iron sights all the time, and it is always right where it should be when I put it back on. The CDS dial wasn't a factor in my purchase, but I sent the coupon in with my load data anyways since it was free. The CDS dial showed up in about a week and the numbers have been right on for summer weather shooting in the areas where I shoot matches. I shot a 200-16x with it in 5.5 minutes in the very first match I ever used it in. When funds allow, I will buy another one for my smallbore rifle. Check B&H Photo and video, I got mine for $750 delivered with the fine duplex reticle.
