Each mount is specifically made for an action and a scope.
The adjustment tolerances are close to zero and it is almost impossible to use an assembly initially planned for an action and a scope on a different action and for another scope without a large work of close fitting.
Despite this, the result is rarely satisfactory.
It is the same for claw mounts as, in fact, the H&H mount is a variation.
Courage ... and good luck!
