I am in the market for a scope for a .270. I have a Leupold VX-II 3-9 x 40 on another gun. Went shopping. They tried to sell me a Nikon. Don't remember which model but told me Nikon had recently improved their glass. Also showed me a Zeiss for less than $400. I like my Leupold but the Nikon was about $100 less. Any suggestions appreciated.
