Parallax and mount inclination are entirely uncorrelated.
Why is turret parallax adjustment better than objective adjustment? Just a matter of convenience?
I've had a new Vortex Diamondback HP 3-12 x 42 here I've been planning to put on a Magnum Research .22, but I was thinking of going with something smaller and lighter, instead. Decisions, decisions...
That's a pretty big scope for a .22LR.
There are plenty of AO or sidewheel scopes out there that are smaller and better suited to that platform.
