I've got and used both types of scopes. From what I've seen, too many think in terms of their AO or their side focus/parallax adjustment doing their focusing for them. Frankly, it doesn't work nearly as well. Particularly with the Leupold focusing system.
Adjusting the parallax will affect the scope's focus. But the focusing needs to be done with the ocular. Works much better.
Maybe some day I'll fool with my hunting scopes at the shorter ranges, say 50-75 yds and see how that works. I suspect it won't work well. I've also got an older Leupold 7.5X AO scope. That may well end up on a new .22 RF. If it does, all the more fun playing the focusing game. E
