Hey Green man ! ,
My experience is limited to a few mfgs. , they are Leupold, Nikon , and Nightforce.
1. inexpensive Leupolds ( below vx3) have exhibited tendencies to not move the poi until a lot of correction is dialed then wham ! your twice too far,
2. Leupolds ( vx3 and mk4 ) have responded accurately to changes and have been dialed way up for a shot then back to zero and they are on . One such Leupold was sent to the Leupold custom shop for target style turrets ( $ 54.00 per dial ) and has performed as it shuold ever since . That was a vx3 4.5x14x40. The mk4 has the exposed style turrets and is like a slot car , in a groove so to speak.
3. The Nikon is a 4.5x14x40 sf( side parallax adj. ) Haven't been out too long but has made a name for itself with me at least . It will do what you tell it to .< over and over and it has finger adj. dials ( no coin needed ) under a twistof cover and it also has revolution gradations marked on the turret so you can range and dial with the big boys and still get back to your zero even if you forget how many times you went around .
4. Night force works as it should , repeatable as a Mk4 , They are on par with the Mk4 's as far as optics and function( I am speaking about one 5.5x22x56 ) I couldn't tell any diff in brightness in the middle of the day . Will have to compare early/late . I will say that I feel like the Leupold has a more refined look about it but that is an aesthetic judgment on my part . I'm not sure the extra dollars for a NF is justifiable .
You might consider buying a used Leupold of the vx3 level and sending it to the Leupold custom shop to have the targer style turrete installed . They are not exposed but for long range work it is not a big deal tio take m off and putem back on when your done . You can als have your reticle changed to one you may like better at the same time.
Just depends on the dollars you want to spend , probably the best deal going is the Nikon . By the way they are bright as or maybe a tad more than the vx3 Leupolds in my opinion .
Happy choosing ! Jim
