I've owned several 760's and 7600's, and all have been accurate, though a couple of the older 760's needed some pressure-relief of the bracket on the front end of the forend rod before they started really shooting.
There's no reason one shouldn't be as accurate as a Remington 700. They use the same barrels, and the action is at least as stiff as a 700 action, maybe even stiffer.
