An insider tip: Sako Optilock mount. The rings have plastic inlays which can rotate some degrees to compensate for uneven bases. If you put a thin shim between the Optilock base and rings, you can customize your cant.
I plan to do just this with my CTR. The scope is a Kahles CBX 3-12x56 FFP reticle 4, elevation max 125cm/100m. Too little elevation for a 20MOA cant, I want to stay near the optical center with my everyday zero (100m zero) for good low light performance. And I want to be abe to click it up to 700m, the max practical range for the .308 in my opinion.
The solution for this excercise in compromising is a 0,15mm bronze shim under the rear-ring.
BTW, I like to optimise/alter/tinker my equipment.
