Windage is bottomed out

Stacking tolerances in something that takes heavy recoil. I shouldn’t have to explain that lol.

If a shim is needed in this application then something is way off.

We too heavy 7 figure pieces of machinery that are shimmed at work. Totally different scenario.

Stacking tolerances? I dont see how tolerance stacking has anything to do with this.

Adding a shim is no different than making a new ring, but taller. Adding a shim of uniform thickness between two solid surfaces that are held down by screws does not make it more susceptible to recoil. Or maybe it does, please explain.

The shims you/we use on industrial equipment are way different than a ****ing piece of a beer can. It will mess with torque settings. Can/has it worked for folks? You bet. So have dodge transmissions and 6.0 fords. Dang sure doesn’t make it a wise idea. And you’re asking for trouble with it. Shimming is an absolutely awful idea. Fix it right. Have confidence in your equipment.

Put them under the back.

Negative. That will only exacerbate the problem

Well, I sure respect your passion.

Passion has nothing to do with it lol. There are folks that come here for honest help. And take some of this stuff as gospel.



Have a great evening

unless said shims cause a significant loss of thread engagement and therefore cause a loss in available clamping force. This can happen easily on a scope mount

But, something doesn't seem right about the elevation being that far off.

Its already shooting to high so why would he put a shim in the back?

[muzzlebrake]

Here is the problem with shims made from aluminum. Aluminum will cold flow over time. Can happen due to heavy recoil and heating and cooling. Happens a lot with aluminum electrical wiring and creating loose connections, arcs and fires. When the shim cold flows and gets thinner then the rings can get loose. Might never happen on a gun that is only shot 4 or 5 times a year but guns that go thru hundreds or thousands of firings it would likely happen.

We used to cut beer cans and make shims to go between the scope and rings.

Ain’t no better way

I ran out of elevation adjustment with the scope on my little 22lr. Only needed it to come down about an inch at 50yds. Took a piece of electrical tape, placed it in the bottom of the rear ring and it brought it up about 6 inches at 50yds. Good to go. Now, on a 22lr I’m sure it will hold up better than something with heavier recoil, but it did the job.
