I'm a big Sako fan. Not so much the newer ones as I think the quality is dropping off, but dangle a well looked after 75 in front of me and I'll probably buy it! I've had a few - .223, .22-250, 6.5x55, 7STW, currently having a .35 Whelen built on a 75 action.
There are lots of things to like. The double stack metal magazine is well thought out. You can drop it and load or top load like a floor plate rifle. It has good capacity. 6, 5 or 4 rounds depending on calibre and is flush fitting. The stocks seem pretty rigid and fit me well. The action is smooth, strong and well made as well as coming in a size to fit the cartridge of choice. The safety is simple, either on or off but there's a button to press if you want to open the bolt with the safety on. And I've never had one that didn't shoot better than I can. 1/2" groups at 100 yards have been easy to achieve with home loads in all four of the ones I've had.
Down side is they are a bit heavy compared to some. That's no big deal really. As far as the ejection issues, I've never experienced it but it could be a thing with the 85's. Likewise with the tapered dovetails, I've never had the mounts shift. I generally use the Optilock base and ring system.
