The turret cap is for rough leveling only.You use levels on the rifle and turrets.
If you lost your reference for gun level, start over.
Here's how I do it.
Use something like a Wheeler gun level.
Make the rifle level (with base level).
Install secondary reference level to the barrel (the V-level), make that level, check they agree.
Install scope, level turret cap with base level (rough level).
Finger tighten scope rings maintaining equal gaps , check the levels still agree.
Hang a plumb-bob, fine tune the scope alignment as needed until the reticle aligns to it.
Tighten scope rings using alternating torque procedure.
Check the gun barrel reference level (the V-wedge level), and the Plumb-bob to reticle, still agree.
