#1 and I would add repeatability/reliability in the adjustments
Plus two!Plus one! If a scope is not consistent and reliable with adjustment returns you've got junk. Repeatability is everything.
Based on the scope testing being done and reported on this forum, I question if that is a true statement. Even with top branded hunting scopes there is always one or two in the arsenal that require re-zero from season to season or even session to session. I always attributed the cause being load related, atmospheric aberration (mirage), shooter error, barrel heat- bedding effects.....never questioning the optics ability to hold POA. Now that I have personally used a scope checker to check a few high-end comp. scopes- one that moved incrementally to a full 5/8" @ 100 yds after just 5 shots-2 other scopes tested moved a tad after 1st shot, then held- I now have serious doubts that most scopes hold POA. Keep in mind I am a accuracy addict, and flyers in any of my rifles are just not acceptable to me.These days, most scopes will hold zero, but not all will last when it comes to having the turrets frequently ran up and down to adjust for long range shooting.
Bingo!One thing we can all agree on when it comes to scopes...the good ones are expensive and the second rate ones are not worth using.
What make and model is your scope checker?Now that I have personally used a scope checker to check a few high-end comp. scopes
Ezell checker. I did not touch the W or E once I got the subject scope to reconcile with the POA as the proven scope. I don't use variable power optics for SR BR.IME I don't see where they are necessary in that game.What make and model is your scope checker?
Can it resolve backlash error to less than 10% across one click on a windage or elevation knob ? Or a 1/10th MOA shift of the reticle about point of aim across its power range?
I built my own because I wanted something that was repeatable to 1/20th MOA. No rifle shoots bullets into groups that small all the time.
The parallax adjustment is not in the scope. Parallax is caused by the aiming eye being off the scope's optical axis. By definition, parallax is caused by an angle between two viewing axes. When the aiming eye is on the scope optical axis, there is no parallax regardless of where the scope range focus is set. Scopes' range focus mechanics (opposite the windage knob or the objective lens barrel twisting) move lenses only in its optical axis, does not move the reticle.if your parallax adjustment can't lock the reticle in perfectly at different ranges,
I am not well versed into the mechanicals inside the scope. But I can insure you that adjusting the Parallax knob on side parallax scopes or rotating the objective bell on adjustable AO scopes to minimize reticle movement at a specific target distance will result in a clearer sight picture and more accurate shooting.The parallax adjustment is not in the scope.
That's true. Both adjust the objective lens system to focus target image on the reticle. Exactly like a camera lens focusses subject image on the sensor (digital or film).... adjusting the Parallax knob on side parallax scopes or rotating the objective bell on adjustable AO scopes to minimize reticle movement at a specific target distance will result in a clearer sight picture and more accurate shooting...

Precise windage and elevation adjustments.
Or...
High resolution of the optics.
