I do too, but it took me a couple months after buying the Caldwell rest before I got off my butt and figured it out.
It works well, for a couple reasons. First, the Rock is heavy enough not to shift around due to muzzle blast. Second, it can be easily adjusted for height, if need be to get the muzzle of a particular rifle in the right place.All you have to do is make sure the muzzle sits just above the V-rest at the rear of the bayonet--which is where the barrel is normally strapped to the muzzle.
