I have had my SS scope for a while now. I have really enjoyed it. It always seems to return to zero. I have it mounted on  a  Savage Mark II 22lr. So when i go shooting it gets alot of cranking since the 22 drops like a rock.
Anyway I took it shooting not to long ago. Did about my normally shooting and normal amount of cranking. Say 100 clicks or so in a shooting session. up down up down for different ranges.  After I got done I decided i wanted to see how much elevation i had left. I think it was 60.5minutes. So I returned my scope back to zero and put it away. I did not fire a shot to check the zero cause it had always returned to zero.
Now I know people cannot make "perfect" products. The machining process is precise but not perfect. I prob did about about 150 moa of adjustments that one day.  Now I know i have cranked ALOT more total than 150minutes since I zeroed the scope, and it always returned to zero  So when i went to shoot it this weekend i was about 3.5 minutes off, but my windage was dead on.  Was that a percentage error of the scope in tracking.  If so that was over a 2% error. which is alot in my opinion.  Or was it something about maxing out the elevation that resulted in the error?

There are alot more factors than the scope being off.  Being that its proven itself before for you I'd say it was more likely other factors that led to your being off.

I just kidna wondering its always been true.  It was very odd that it was off that much. I felt that if something else had changed botht th windagea nd elevationwoudl be off.  I hope to run it through its normal paces this coming last this weekend. See  how it does. I didnt get "shoot" this weekend. Last time i had to just figure out was wrong then redo my zero.

Be interesting to see what your next range session gives you.  Is this on your 22?

Yea its on my savage  mark II 22lr. The i checked the turrets when i realized it was off. The 3 screws on theleavtion were snugged up tight.  the windage was lose enough that it wasthe turret woudl sping without clicking. So I tightn the screws on it. windage wise the bullet was dead on. yea took my fat wrench and went through and checked the action and ring screws. Everything checked out.
This being a holiday weekend I m going spend alot of time shooting. It was easliy rezeroed I just seemed like a fluke. I dunno Ill update you all next week i guess.

Me thinks it has lost it zero a couple of sessions ago, and this was your first zero check in a while. So the 2% loss could have been accumalated over a couple of sessions.
 
I think the standard is to check zero before any serious shooting starts. If it shows a zero  loss each time the session starts, something more could be wrong.

With a 22 you could find that the ammo from different lots behaves differently.  And in a calmer wind day your windage may be still correct but the ammo being loaded .01% differently in that lot could account for less velocity and hence more drop......... to many factors with a 22 to rule it down.
