Scope leveling

[JGRaider]

There's plenty of chance for error using cheap bubble levels, that's the point you obviously missed.

FYI, those wheeler levels have adj screws. Swing by a machine shop and ask if you can verify it on their rock or with their Starrett Level..

Error in using them for what, mounting the scope or confirming reticle is plumb at time of shot? The point is having a reticle perfectly plumb to bore doesn't mean shit if you are holding over/dialing and your scope is not plumb to gravity at the time of shot, which can only be known if you have a scope level.

Are you saying when a bubble level is torqued tight around a scope to read level when the vertical reticle line is plumb, that it reading as much is not repeatable? Or that the bubble level shifts in it's housing? I could see some third axis issues possibly on steeper up/down angle shots but otherwise i'm not following the concern? Cheap bubble levels on a turret or something to physically level a scope, i agree, and thats the drum that's been beat to death on being a waste of time on these threads yet people keep looking for gizmos to do stuff that doesn't matter.

Edit to further clarify - 2 posts ago it seemed you referring physically levelling the turrets of the scope. The important part is that the reticle and tracking direction are plumb, if the top of the turret are a few degrees off from that it shouldn't matter functionally as long as the reticle is set plumb when level indicates level.

Spot on -- though I'd refine that a bit to something like 'weapon level' or 'field level.'

Having a level that depends on both it and the rings staying 100% in place on the tube concerns me. Rail mounted or integral bottom ring level designs should allow me to see when/if my scope somehow rotates in its mount.

Agreed, which is why the Reticle-Tru is fool proof.
