Interesting article on the manufacturing processes involved in making the really big high pressure gun barrels. This involves either compressing inner layers of the gun barrel by shrinking outer layers onto them ("built up gun") or achieving the same goal by compressing the inner layer hydraulically in stages ("autofrettege").

Its a good read. I picked up a lot on how and why the big guns are made the way they are. Also tidbits like the barrel liners have to be drilled out to recondition the gun. Never knew that.
