Bushnell 4200 Elite Tactical 6-24 X 50,
decent zoom range, Mil dot, Large lens for lots of light and clarity (for the price), Resettable Target turrets. You dial your scope in for your common yardage then loosen the turrets and lift/turn them back till they read zero and re tighten them, wa la. You now can adjust your scope for a new yardage and just dial it back to " zero" and be back on the money at your common yardage, AND it can be had usually for around $700
Best bang for the buck. Lens wise it's not a big dollar Leupold or Night force but your not paying that price and it does come right back to zero time and time again.
