I've got the M85 in that caliber and like it alot. IMO, In stock form the CZ527 is a little nicer rifle but is a few hundred dollars more and by design doesn't lend itself to customizing.

For me if I wanted to buy the rifle and use it bone stock the CZ527 would be the way to go. If I wanted to do a little custom work down the road, i.e. trigger, stock etc. I would probably pick the M85.
