“I have some engineering friends and they want all scopes perfectly level and uncanted. Using a @badgerordnance "dead zero" scope leveling tool with rail, you can perfectly level a scope with mounts using its built-in bubble level and fine adjustments. Then you look through scope at a plumb line or other vert/horiz point of reference and rotate your scope so there is no cant in reticle. In this case, we looked out back of kitchen to reference lines taped to backyard wall. You can do this directly on the rifle as well if you level that but it can be a lot trickier. This is also a good time to mount a level to the scope for when you are out shooting, as you know it will be perfectly aligned without cant. I found this pretty interesting of a process!”
