Is this acceptable for high end rings? And a couple other questions

[SomeJackassOnAForum]

It is clearly unacceptable to you, so why does it matter?

I looked at some of the rings with levels built in but I just don't think I could trust them that much.
Ill just use the tube mounted levels. Pretty simple and jsut easy. If its wrong its probably my fault and ill take that because I can control it.

I do see the possible benefit of the ring mounted levels on a hunting rifle as they are out of the way from getting caught on things etc. But there is a chance for issues with about everything.

@ssimo

Have you come to grips with how ridiculous this whole thing was by now?

Not once did you mention reticle plumbness relative the bore as being your worry. But if that is your worry, I'd just like to say that is a largely overblown issue

0.5° cant error with a 2" height over bore zeroed at 100 yards is a windage error of 0.017" per 100 yards.

So if you have a perfect 100 zero on your 450 yard rifle, it will have a built in angular misalignment causing a 0.061" windage error at 450. Less than a 1/16"


It is not impossible. Simply not financially feasible. As the math shows, there is no practical advantage gained by a dead-nuts perfect level. And to manufacture such a level gets expensive fast. Stuff like that doesnt sell. If zeiss does manufacture such a thing, tickle me impressed

but most importantly, I am not a huge fan of scope ring levels. They are not as easy to see as an offset

With your example of the reticle being out of plumb with the bore, does it extrapolate linearly? For example, if it is off by 2 degrees, would your windage be off by 4 x 0.061" at 450?

My reticle is leveled to my tube mount level just right (actually set up to where the bubble rests on the left edge of the level line for easier quick check and less head movement) but I just realized yesterday that my reticle is not plumb to the bore. It could be off by 2-3 degrees. I'm really not wanting to remount and rezero, but not sure how much error it would create at my max of 600ish yards and whether or not a steep uphill or downhill angle would increase that windage error.
