It changes from time to time
SO…. I broke down a 39A (that was shooting well) to give it a good cleaning & when I put it back together I snapped off a base mount screw in a set of steel Weaver tip off rings. I blame it on my Wheeler Engineering gunsmith screwdriver kit. Replaced them with a better set of steel rings (Burris) and figured it would be close to on because I didn’t change the previous scope settings. So much for that. It was a stable platform but shot so far low & left I ran out of clicks on the Nikon 3x9 Target EFR. Not the scopes fault. I was amazed it let me move it as many clicks as it did. It started out 18” low & 6” left at 35 yds & wound up 4” low & 2” left when I ran out of adjustment.
