Scope cant drives me nuts. I'd trust your level on the bases as others have said. I use a Wheeler Engineering kit/Fat Wrench levels and I've found that elevation turret caps are not always true and reliable, so I stopped using them as a reference.
The other thing I've found is that just when I think I have everything level and then shoulder the rifle to check eye relief, etc., the scope looks like it's still canting left. Everybody'd cheek weld is different, I guess.
Nice 700 VLS. Does yours have the fatter beaver-tail stock or is it the older conventional one? I had one of the latter ones chambered in .22-250. Bought it new in 1996 for $369.00! Like a fool, I sold it.
