I am certainly no expert but if your reticle is solid and your turrets can return you to zero then you are good. The really expensive scopes generally have the better optical quality, are tougher towards abuse, have great customer service and superb reputations. There are good "cheaper" scopes out there with good reputations for holding up too. The proof is in the tiny shiny spots on your metal target at 1200 yds.
Do this: set a target out to a compfortable distance where you know you can hit the bulls eye, calculate the number of clicks on your turret that would give you a 6" change both verticle and windage. take a few shots at the bullseye (hopefully hitting consistanly for your expected group) then click your 6" up, shoot a few or one, 6" over windage, shoot a few or one, 6" down, shoot a few or one, Then finally 6'' back to the bulls eye and shoot a few. you should group right in your original group. BUT Remember, and this is very important. let your barrel cool down after every 3-4 shots otherwise you might see some slight to big changes that have nothing to do with the scope. Some guys run cool water over the outside of their barrel if they have a free floating barrel in a fiberglass or composite stock. Don't do this if your stock is wood or your barrel isn't free floating, just let it air cool. I have never tried the water cooling except when its raining LOL
