All though I have only shot about 40 round through my new .308 rifle with this scope, It sited in very easy. I was hitting on the outer edge of the target from the box at 50 yards and center in about 6 shots. Moved to 100 yards to zero in. In about 8 shots I was grouping with in 1.5 center target.
Pros: price, accuracy and ease
Cons: Not sure yet, site get fuzzy at full power,
