S&B Zenith scopes

[dirtboy]

Anyone hear have A Zenith 3x12x50or 2.5x56 . I have a browning 300wsm and I was wondering has anyone put the turrets on this scope like the percision hunter. or if you have a percision hunter what kind of addtional range can you get out of the turrets just on the center cross hair? I plan to buy a Zenith and have them put the same turrut system on there as the percision hunter model. I just want to know how much it improve this range of my 300wsm aboutgun)
