It's old (not sure what the OP's final fix) but found this FYSA ...

I bought a cz550 in 416 Rigby last year. The action is perfect. The trigger is amazing. It shot dead on with the iron sights. The only problem I had was that when I mounted the scope, it shot way too low. I adjusted the scope as far as possible, still not enough. I contacted the company, and was told that they never really intended for the big bores to be used with a scope (why the mounts then????), but they offered to replace it no questions asked. I hated to do that because I had already had the action glass bedded. I honestly think that the problem is with the rings (also cz, but they don't measure the same height), not the action. I'm going to try a different set of rings and see if that fixes it, but for now, I just put a .020 shim under the back ring. Works great. It will shoot under 3/4" at 100 yards with both Norma and Hornady ammo. As a matter of fact, I used it to shoot a five point bull elk last year. Poor bugger never knew what hit him.
