I have two M77's and neither were free-floated. Just got the scond one last weekend, a .257 Roberts, and free-floated the barrel a couple of nights ago. The 7mm Mag shoots .5" groups and the .257 Roberts shot a 3-shot 1.35" group. (Not real happy with the .257's group, but it was the first time out, only had one box of factory 120g ammo for sight-in, and a trigger that definitely needs work. Cosmetically speaking, the gun is gorgeous.) The 7mm Mag has 20 years of hunting behind it but still looks great.
My buddy had a newer M77 MKII 7mm Mag (circa 1999) and the first thing we did to it was free-float the barrel. He gets .4" groups with it. This gun has some of the nicest wood I have seen on a production gun, and the metalwork is up to Ruger's usual high standards.
My new (Christmas present) Ruger M77 MKII VT is fully floated and has a target trigger. Yesterday at the range I fired two 2-shot "groups" at 200 yards, adjusting the scope 3 clicks up between groups. The first measured 0.275" center-to-center, the second measured 0.475", and there was 1.5" difference in height between the two (as expected). No probelms with this gun, functionally or cosmetically.
As to the Savage rifles, I just got rid of a 110E in .22-250. Although that gun shot great when I first got it, the barrel was toast. And it was, as my daughter says, "ugly". Plastic trigger guard and front sight ramp, birch stock (not bad for function, just not pretty), poorly finished bolt handle and bolt raceway, etc. The newer Savage rifles are much better looking, and still shoot.
My personal opinion is that its hard to go wrong with a Ruger. The triggers are lawyer-inspired, but so are most, and they are easy to fix. Cosmetically they are one of the best looking rifles available, IMHO, and every one I have worked with has been a shooter. (The jury is still out on the .257 Roberts, but I haven't touched the trigger, haven't worked up any loads for it and have only tried one factory load.)
