Been using the Rem. dry lube for quite a while and I find that it works well for me.
Made the difference one cold late-winter elk hunt - the temperatures dipped close to -40 during the day, and my rifle functioned properly when it counted. Couldn't say the same for my hunting partner's rifle, though (I have no idea what lube he was using, but that "click" of a misfire can get awfully loud!)
