This weekend I took my Ruger # 1 to the range to get a 100 yard zero on my new Zeiss Conquest 6.5-20. As I was getting close, I ran completely out of both elevation and windage adjsutment. I was left with a "zero" of 2" high and about 3/8" to the left of dead center!!! I mean no additional donwnward or left adjustment was left in the turrets!! I have never had this happen with any scope before. The Leupold 4.5 - 14 I took off the rifle certainly did not have this issue. I am using the same Leupold rings for the Ruger quarter rib as before. How could this be so far off?? I guess I am wondering how concerned do others think I should be about this, and do any others have similar experience? I am truthfully more worried about the windage, as I plan to get the rifle zeroed at 300 yards and dial up from there as needed. For less than 300 I will just hold dead on and squeeze the trigger. I did this with the Leupold and liked it that way. I usually use the mil-dots to hold off for windage, but would like the ability to dial it in if I choose. Also, if I am about 1/2" left at 100, I should be 1.5" left at 300, 2" left at 400, etc. Right?
