How do you guys level scopes?

[rabiddawg]

I set the rifle in a vice or holder and use a bubble level to get it level. Then I hang a plumb bob in front of my door. Then shine a flashlight from the objective end of the scope to project the reticle onto the door. Focus it by using the reticle focus ring. I put another level on the scope turret just for reference. Then I turn the scope until the vertical line and plumb bob are aligned. Snug down the rings and double check before torquing them down.
