The "sloppiest" bolt-action rifles I've ever handled were military Mausers. When the bolt is open all the way, you can wiggle it up and down at least 1/4" at the back end. But they're made this way on purpose, so they will work when filthy and full of sand! The best I've seen for military rifles were thedouble-heat-treated 1903 Springfields made after WWI.
By far the smoothest commercial, production-linebolt riflesever made were the Mannlicher Schoenauers made in Austria with diamond-dust honed actions!
Maybe that's why I don't think it feels wobbly? I'm quite used to the military rifles and no what you are talking about. I think mentally, that is probably one of the reasons I bought the Ruger All-Weather. It's butt stock resembles that of my M-16A2.
