No, I did not count the Buckys "fixed" Leupolds.

The only dumb question is the one not askedI just wanted to thank the OP for starting this thread. I to have an Sightron SIII 10-50 x 60 and have been having a Little trouble shooting consistent groups. I have felt it was something I was doing at the Bench and now I feel that it was the parallax adjustment on the Scope causing 70-85 percent of my trouble. I believe I will be shooting tighter groups now.
Thanks
