Just get the rings screw not quite snug and set eye reload and align the reticle. Whatever way you do not is fine if it works. I mount a lot of scopes and can eyeball the vertical posts with the butt stock very close.
Then ensuring that the scope doesn't twist, tighten the ring screws. 18in-lbs is what I generally do. Any less than about 16in-lbs and you sometimes see slippage. The little end of the wrench is good for this.
Once that is complete spin the power ring and parralax knob if it has one and spin the turrets up and down. You're just looking for binding or anything weird. If it's good, you're done.
