I was humming and hawing between a cz550 in 300 wm or a win 70.
I ended up with the cz550 and I love it.
I'm sure I likely would have been just as happy with the win 70.
Bear in mind that mounting optics can be just a little trickier on the CZ due to the bolt throw. A leupy fit mine with medium rings (barely) but the Zeiss required high rings.
Also, the rings are proprietary, so sometimes finding high rings can be just a little tricky. Clay at prophet river ended up getting them for me.
It is nice that you don't need to mess around with a base though. I also like that I can just pop the scope off if I need to and the irons are ready to rock. The win 70 I was looking at did not have irons at all, so that is what ended up making the decision for me.
Edited to add: sorry I think that I might have been a little confusing describing the scope situation. They were both 3-9x40, but the larger ocular bell on the zeiss interferred with the bolt handle with medium rings. This was not an issue on the leupold....
