It should be as simple as level the scope to the action and tighten it all up, but it isn't for me. I shoot off of rests and rear bags 98.5% of the time and have take the stock into the equation. My rests even have levels on them and I also run a scope level so I have to level the level to the level. I just gave my self a headache.

I typically cant a rifle a few degrees, so most of my scopes are not 90* My pistols and LR rifles are set at 90*, one of the biggest issues is that some scopes are not even built 90* to themselves. I’ve had several well known high dollar brands that do not have the crosshairs perpendicular to flat spots on turret assemblies, as well as some picatinny rings that do not clamp perpendicular to mounts.
It is definitely a process and nothing is simple.

Eye relief comes before reticle leveling.
My technique for leveling a scope is to shoulder mount the rifle offhand, from starboard & port sides, viewing reticle against sky or neutral light. Keep focus of short duration, not longer than one breath. Drop to ready-gun or port arms. Repeat. The rings have barely any friction at this time, so it is easy to rotate minuscule amount. To hold focus too long invites optical illusion.
I alternate tightening rings screws, similar to torquing a cylinder head.
Some rings----the old Weaver rings with stamped steel top ring are a notorious example----incline to rotate scope as screws are tightened. That claw & screw system requires “timing” the reticle to rotate toward the screws as the screws are tightened.
Perhaps there is a bore sighter which helps level the reticle. Tried several Bushnell bore sighters years ago, did better by trial-and-error. David Bradshaw

I Also set eye relief with optic set at highest magnification, it is at its most critical at the high end. I typically close eyes and then open them with every shoulder mount, that way the little micro adjustments you subconsciously make during setting eye relief do not take place or at least are kept to a minimum.

Not to mention the tedium of reaming or lapping rings which most say is unnecessary in all but the most critical benchrest applications...
Then why is it so difficult to find a used scope without nasty crimp marks in the tube?

Action flats aren't level Rails aren't level Scope bases aren't level Turrets and caps aren't level Crosshairs aren't square to anything The best way I know of to truly level crosshairs is to put this on and line the vertical crosshair up with a plumb bob on a string. It finds the true vertical plane between the scope and the bore.

Plum bob and a reasonably level rifle.
I agree with Mr. Bradshaw, eye relief first and foremost. Setting up rings in the right location. Some scopes will not tolerate having a ring too close to the turret or the magnification ring, all kinds of issues can arise.
I generally prefer picatinny rails when possible. They allow spacing and position options a fixed set of rings do not. Also, the ability to chose built in MOA slope in mount can give full use of a scopes internal travel for a scope with repeatable turrets.

Apparently level at home is different than level at the range.

I swapped a couple of Redfields on to two different M14 rifles just today.

I don't hate it.
I really like rifles and load development and mathy optics problems.
I also have a machine shop at home and I can shoot well past a mile, literally right off my front porch.
There's the lure if immediate returns on my efforts - but still, I like it.

They could actually be used as a clinical psychological test for patience under stress or some such. Yet I'm to cheap to throw them away and end up using them a lot ,,, and cussing every time . Go figure. Some of my Weaver ring sets have worn out several rifles . True re-cycling in action
