Out of elevation at 30 yards

[JungleShooter]

Thank you for all the advice i ended up shimming the rear ring and its got me back on track.

I will be buying a set of the adjustable scope rings in the near future.

Chip,

when you're ready to make your purchase, here's a Scope Mounting Table with the specs of about 20 different options of adjustable mounts:

Prices, mounting height, maximum elevation adjustment, windage adjustment, QD, and other peculiarities.



If your scope is not 30mm but 1" or 34mm, the table still lists the brand names that offer sizes other than 30mm. Just google them.

As gunsmiths know when shimming scopes on powder burners the shim goes between the bases and the receiver .

You would already know that though ....

So yes , I'm calling B.S. on you

ANY shimming would cause a misalignment of rings. Simple geometry. The question is would it cause damage. I prefer not to take the chance.

To illustrate the issue, take a ruler and place it on a piece of paper. Draw a 1" line along the top and bottom at one end and the same at the other end. Then raise one end of the ruler (as would happen with a shim under the tube). Does it look like the tube would remain in flat contact with the rings? Doesn't appear so. And in the case of shimming the entire ring, it seems that would produce a situation where the entire "shimmed" ring is higher (out of alignment) than the non-shimmed ring. In other words, still "parallel" but now offset.

Will shimming produce elevation change in a scope? Certainly. Is it a good idea? Some think so, and some don't.

All IMO, of course.
