Would it be impertinent to ask what its for?
Just as an experiment to make the most powerful individually operated rifle, I suppose there is some value, but that thing would be at its best mounted to the bed of a truck. Loaded with a high BC bullet, long range shooting might be more it's forte than as a hunting rifle.
