Thread: Scope running out of elevation adjustment (Shooting too high)

Hi team,

I have a Weaver Grand Slam 3-12x42 with side focus.

At first I could not hit an A4 paper at 25m, then I realised it was shooting way too high.
After dialling the scope to the end of its elevation adjustment limit, I was still shooting about 25cm high at 25m.

Tried setting it up on a CZ452 22LR as well as a T3X in 223, with different rings, both with the same result.

Did a search on the forum and saw a few similar previous posts, which suggested swapping the front and rear rings around. I tried but it did not help.

The only trick I can think of now is to shim the rear rings of the scope using a piece of coke can to drop down the point of impact. However some posts suggested doing so may damage the scope.

So my questions are:

- Will shimming using a coke can piece be too risky?

- Should the shim be inserted between the scope tube and the ring? Or between the ring and the base?

- Does wrapping the shim in some clothes to provide a softer contact area sound like a good idea?

- Any other suggestions?

Thank you very much!
