I bought a new tikka t3 and must say that I am thoughly impressed with the accuracy, however, I have a concern with the scope mounting/set-up.

I took the factory rings (which I thought were fairly flimsy) off and bought a set of weaver bases and mounts here locally and had the shop put everything on and bore site it. The good news is the rifle shoots extremely well and cut one big raged hole with 3 out of 4 shots. The bad news is the hole was approximately 13" high at 100 yds.

Nowthis wasn't a "sight-in" session at the range, I just wanted to see how it grouped, however, I'm afraid that the scope (slightly older leupy vari-x II)is not going to have enoughrange of adjustment to bringthe shots down to an acceptable height. the shop guys mentioned the word "shim" and I shuddered slightly.

Although I have never had to "shim" a scope before, it gives me the mental impression of something "half arsed". Now this is probably not the case at all, but with the potential accuracy that this gun can obviously produce, I don't ever want to be worried about something like this "failing"at the wrong time.The guys at the store didn't really have too much time tonight as they were closing. Can you guys explain how the "shim" works and comment on its reliability over the long term? I'm not even sure what exactly itcould be shimmed with. Thanks
