Addendum.
When the guy's scope failed, I watched while another shooter loaned him a scope, and the two worked feverishly for over an hour and through a box or more of match .22s (Center X) trying to get it zeroed.
While I watched, they slipped mounts on and off and cranked away on their wrenches. Meanwhile, I'm thinking stresses!
Point is, learn to mount a scope properly or find someone who is competent to do it. It doesn't take a degree in mechanical engineering or special tools, but you do have to have a sense of geometry and be able to visualize potential sources of stress.
Poorly mounted scopes are a major source of vexing accuracy problems, and many a shooter is oblivious. As Stick would say, Hint.
