I own two Sakos and I love them. I have a problem with my 75 Stainless Synthetic in that it doesn't feed Federal ammo very well, but many think that the problem is with the batch of Federal brass because the gun feeds every other brass with no problem.
Groups average well under 100 yards and, yes, the barrels are free floated. As for the trigger, yes, it is adjustable from 2 to 4 pounds, like the Tikka, and it is VERY EASY to adjust. I adjusted mine down to about 2.5 pounds.
Sakos are excellent guns, but they are expensive. On the other hand, while Tikkas are also excellent guns at half the price (and I own 3 Tikkas) the Tikkas have more plastic in them than the Sakos. The Sakos have 100% stainless Steel internal parts - you pay for quality.
In my opinion, between Sako and Weatherby, I would buy the Sako.
