My SS M70 FW All Terrain '06 is the one I consider most reliable. Only because I have had it for over 25 years with no problems and use it more than any other rifle I own except my 10/22. Horseback, bicycle, coastal salt mist, freezing rain, high desert dust, It worked in all of it.
The SS All Terrain Rugers have never bobbled, Neither have any of my Model 98's. For that matter both my Kimbers have always worked. There aren't many bad ones.
Model 70's in general are very reliable. I did have one safety get awfully hard to work after a reblue job and a.338 fail to feed after Irestocked it. Both user induced problems though.
I have had extractors break on 700 Remingtons and on an early 110 Savage and I have seen a couple of Model 700's with so much gunk inside the bolt they wouldn't work.
