I have a Sako 85 Finnlight 300 WSM
and I will never buy another one. It shoots anywhere from about 2-4 MOA. Have sent it back to tfactory 2 times now with no satisfaction and told by Beretta that it's fine and the next time I send it back they will charge me. It id almost impossible to find after markets parts and accessoires for them and IMO they have poor recoil lug design/system. if you get a good one, it will shoot well, but if you get a bad one you're stuck unless you sell it and if you're honest about it, good luck getting a good price.
I've read some things about the Savages, but my first choice in a factory rifle for a WSM cartridge would be a Sub MOA Vanguard. The actions are made by Howa and they come with excellent, solid, pillar bedded stocks. They come with a factory shot target with real bullet holes and should easily make 600 yd plus rifles. A SS goes for about $830 on gunbroker.
