To answer your first question, yes that bolt face works with those calibers. To answer your second question, well that's rather subjective. Do you mean bolt throw after you fired a round, or just cycling the bolt and the lift feels heavy? If it's the latter, they are 6 lug actions so it takes more force than the 2 and 3 lug 700 actions to cycle the bolt. It will break in with use though and feel much smoother over time.
