Kirby was seeing about 1/4MOA vertical when he first put my rifle together. It took him a while to figure out, but the rings where moving a couple thousandths forward and back on the Picattiny rail. So he added 2 more rings, so 2 are at the front of the slots and 2 are at the rear. The 338AM has a bit of a bark, and with that huge muzzle brake, the recoil is a back and forth motion that is tough on scope mounting components. I can't complain, as the recoil is really gentle and with better than 7000lbs of KE at the muzzle, a non-existant recoil is simply amazing.
I've thought about taking it apart and trying to shim it so I could get rid of 2 of the rings (and use them elsewhere), but it shoots so well I can't force myself to touch it
