Very well done and of course the low mounted scope sets it off nicely (high mounts being my absolute pet hate). I like the understated Leupold on it too, not sure why you would want or need to change out to a Zeiss?

Personally I would push the 140 grainer faster than 2750fps, the 7x57 equaling if not surpassing the 7mm-08 which easily gets 2860fps to 2900fps from a 22" barrel. I currently load for four 7mm-08's in the family and have in the past loaded for and hunted with a classic BSA Hunter 7x57.
