I speculated that that was the reason for it but I never actually saw a scope mounted that way. I'm curious if many folks do this to try and ease loading and help thwart ejection problems. I must say though, I have shucked a lot of brass from bolt action rifles and don't ever recall a windage turret hindering ejection unless it was a target knob
Just like Utah708 said, it's to keep the turret out of the way of loading/ejection. Actually, for myself anyway, it's pretty much to keep it out of the way during loading - it's amazing how much a windage turret in it's "normal" placement encroaches into the loading/ejection port. I mount all my scopes this way.
