I've mounted all my own scopes for the last 30 years. Someone else will never mount the scope correctly for "you" due to your eye relief needs and physique compared to someone else.
It sounds like the mounting you performed was correct. However, did you check for proper eye relief?
Here's how to check:
1) Put your scope on maximum magnification with scope all the way forward in loose rings.
2) Put the rifle to your shoulder with your eyes closed.
3) Open your eyes and look through scope. If you can't see through the entire scope (i.e. no black around edge of optics), slowly move the scope rearward until you can see fully through the scope and try the closed/open eye sequence again.
4) Tighten rings after levelling scope/rifle.
This procedure will give you the most eye relief for your scope and a guarantee that you will have proper eye relief on any magnification setting. Eye relief is most critical (shortest) at maximum magnification. Most hunters don't do this and this is why the scope hits them in the face with higher recoiling rifles. Good luck...
