Just because you level one, doesn't mean the other is level.
The easiest way to "eyeball it" is to take your bolt out and line your eye way out behind the gun, and you'll be able to see the reticle. Line it up so its bottom post is directly at the center of your bore.
The easiest non-mechanical way to level it is to level your gun as best you can, then use a string/plumb bob to align your reticle.
Then there is always the feeler guage method, if using a 1 piece base and the scope allows.
