I kave a cz 452 hmr and took a bit of care when first mounting scopes. have 2 that i occasionaly swap between.
I dont really have faith in the zero being held after removal, but having said that, I have not needed to adjust after
swopping!
Next time i fit a fresh scope and rings i think it will be rings on rifle, then a bar and lap them a bit to ensure they are straight, then fit scope after scrupulously cleaning mateing surfaces.. after that, there will be no reason for zero to shift after refitting
