AO scope
What's the advantage of an AO scope? I'm going to put a scope on my CZ 455 .22LR for plinking/targets/spinners & squirrel hunting. Was thinking a Leupold VX2 3-9x40 or a VX2 4-12x40, shots will be 100-150 yds. tops, most will be inside 75 yds. Any ideas?

For your 75-150yrd plans, no need to get adjustable objective or side focus. Parallax error is a very real offset, and it really doesn't matter how careful a guy might be, nobody lines up perfectly the same, every shot. Parallax correction ensures the crosshairs are covering what they appear to cover (minus mirage), but the error is dependent upon the difference in set range and actual range - for a 100yrd fixed parallax, there's just not enough to worry about for 75-150yrd hunting/plinking/pleasure shooting.

Our pellet rifle has a 4X↔12X scope on it. It is very useful to have the AO when it is set on 12X. The target is quite blurry viewed through the scope when shooting at various ranges from 'short' to 'far'. Being able to adjust the objective is a very very good thing; we would hate to shoot using 12X if we didn't have the AO. With the scope set on 4X the AO isn't a big help.

So if I'm shooting a 4-12x40 at 20 yards or at 150 yards, I'm OK not to have the AO?
In order to get the scope when set at 12 power to focus on the target at ANY range it is advantageous to have the AO. That is what my experience is. When set on 4 power, the AO isn't hardly needed. The reason i shoot a lot is because i enjoy shooting. If the 4x↔12x scope didn't have the AO, i wouldn't enjoy the shooting as much. ☺

The AO will be handy on any scope. Most non AO scopes come with rhe parallex set at around 100yds. On lower power scopes we do not notice small differences in cross hair movement or focus but it is there. On higher power these things become more pronounced just like any movement when trying to hold steady. I have a 4x16 sweet 22 scope with AO even on 4x and shooting at 10yds the AO cleared that scope up a lot. It was stated he wanted the scope for every thing including target shooting. In my opinion get the AO and have no regrets and remember low power does not make parallex go away.

I mis-read your original post - I misinterpretted that you'd be shooting typically at 75yrds, but out to 150.
If you're shooting UNDER 75, as in 20yrds, you're going to have risk of parallax error. It won't be much, since even 1MOA is only .2", but it'll be there.
