I agree with 84jim. You are not going to see much difference in optical quality between an $600 scope and a $2000 scope. 98% light transmission is all you will ever get out of a scope regardless of the price. Its the inner workings that make the difference. I have been deer hunting for 25 years and I have never touched the turrets of any of my scopes except to sight them in initially. If I were into 1000 yds bench rest shooting, any kind of long range shooting, or even prairie dog hunting in some cases, I would constantly be adjusting the turrets for ranges and then setting them back to zero. You are not going to find too many good quality scopes in the 4-16 power range or better, with 50mm obj or bigger, with mil/mil reticle/turrets, using first focal plane, with 98% light transmission in the mid range scopes. The vortex viper pst line is probably the closest thing you will find.
