I can't imagine any accuracy issues with a rifle built on the Ruger action. All them I've owned have shot well save for one with a custom barrel that turned out to have a seriously loose spot in the bore. Another barrel took care of that. As for a comparison with the Hauck action, I think all the advantage goes to the Ruger. Internally they're nothing alike, and the Hauck is so large and heavy that it's not possible to make a graceful looking rifle with it. And, they sound like a Sherman tank when they're opened and closed.
