How can a "soup" of molten metal poured into a mold be strong enough to become a rifle action that must endure such high pressures?

Obviously the Ruger action holds up, but not understanding how it is done causes me to not have full confidence.

Can anybody put it in laymen's terms?

And to add to the confusion; how can/does Ruger make an investment casting stainless all that strong?
