Rifle Scopes Chassis Bubble level, Spuhr bubble level

[A5scott]

So, my Masterpiece Arms build has a bubble level built into the chassis, and I had a NF unimount with a gen 2 razor in it, and put about 750 rounds thru that setup, out as far as 1680 yards, and decided I wanted a Spuhr, as I'm a lefty and my brass are hitting the 3/8" nuts on the NF mount on ejection.

The bubble level on my rifle is centered, and the bubble level on the Spuhr mount is touching the left side line. My previous setup with the NF mount was verified out to distance, so I'm thinking my rifle is fine... Is it normal for the two levels to not be giving the same indication?

thanks,
Scott

It really does not matter. You need to get your turrets to agree with one of them, then stick with that.

I’ve got an MPA and Spuhr Mount. When my rifle is level, the Spuhr bubble is centered, and the MPA bubble is in the center, but touching the left line.
I’m a lefty as well, and can’t see the Spuhr bubble easily.
I know that when the MPA bubble is touching the left line, my reticle is level.

thank you, and did you use the Spuhr leveling wedge to level your scope?

Yes, I used the wedge that came with the Spuhr Mount. It made the leveling process simple.

 

[A5scott]

yes, same here, but the vortex razor illumination turret is giant, and it's almost interfering.

 

[A5scott]

ok, I moved the scope forward a bit and the wedge clears the knob

This is going to kill you if you have bad OCD but...did you level your action to your chassis? Meaning, did you compare horizontally true surfaces on both action and chassis as you tightened the action screws? My dumb ass will place one straight rod on the pic. rail and another on a reference point (whatever you trust to be flat and perpendicular to the chassis centerline), and compare those two as I torque the action screws. Takes forever and gives me a headache but I've got that warm fuzzy feeling knowing that the points are as parallel as I can make them.

Lowlight posted a video about this a while back. It doesn’t matter if the rifle is 100% level. It matters that the scope is level to gravity.
What you don’t want is a perfectly level rifle that doesn’t fix you, so you end up fighting it or uncomfortable.
As long as the rifle is reasonable close & the scope is perfectly level, your good to go.

my smith is pretty ocd installed it, but probably not a you described. I've shot it out to 1680 before and it was on, so I'm thinking it will be about the same with the new mount, as long a it is level. I can level the spuhr mount to gravity, then check the MPA bubble level and just hold accordingly.

yes, I've watched that video, I didn't realize what I'm experiencing is that
thanks again
