I am now thinking of a second one for my back up HFT gun, after at last having some decent scores this last year or so. I have a lot of confidence in the scope now, and find very little PX if I pull my eye into the scope a bit. I have mine set at 23 yards as I find the closer stuff a bit blurry any higher. They are so crisp you know exactly where your PX distance is.
I zero my turrets as well, and it is then not such an issue if or when, you knock them round a bit.
