Scope mounting

So, when I'm trying to level my crosshairs when installing my scope, I'm not so concerned with the crosshairs being perfectly level with the action so much because my most comfortable hold on the rifle might be slightly canted? I'm thinking that I need to be in a repeatable, comfortable holding position and level the crosshairs at that point and install the level ring thingy to be able to repeat? Asking for a friend. 😁
