I recently found a deal on a Weatherby 30-378 Accumark that I couldn't pass on. The gun came with a Zeiss Conquest 3x9x50 scope with Leupold rings. I bought this gun to replace my Ruger M77 338 Win Mag that has a Leupold Vari-x-iii4.5x14x40 that I really like. I have no experience with Zeiss but told it is a good scope. The thing I like about Leupold is I can have a custom dial for the round I'm shooting, the altitude and temperature so I can range the target, and dial in the yardage and then hold on. Not sure Zeiss has that option. So, my question is, keep the Zeiss or replace with the Leupold?
