I have a SB Classic 3-12x42 #8 mounted on my .257 Weatherby Accumark.
I did a bunch of homework on many of the high end scopes (Swarovski, Leupold VX 7, Zeiss Diavari and the SB) including field tests in daylight, dusk night and overcast/rain. IMO, the SB and Zeiss Diavari were extremely close with and edge to the Diavari only in total darkness. The Swarovski did nothing for me and I couldn't bring myself to pay $1500 for a Leupold VX 7.
I bought the SB because of the contruction and what MANY others had told me about their durability. I absolutely love the scope especially the FFP reticle. I'm about to finish my first season with and I love it. As many others have said, you will not be disappointed. I wasn't and just ordered my second one for my .300 Weatherby.
Good luck!
