Speaking of rifled artillery, Dan Gallery was the commander who captured U505 in WWII.
He wrote some very funny books after the war and recounted this story.
The ship he was on would cross the equator and he put out this memo
"Scientists studying the coriolas effect have theorized that a fine stream of liquid will have a twist. North of the equator, this twist will be in a clockwise manner, and South of the equator, the twist will shift to counter-clockwise.
" we shall cross the equator at noon today. All hands are encouraged to test this theory and report the results.
"The rifling of the instrument determines the twist."
"Twisting the instrument controls the twist of the stream."
"Smoothbore. No twist."
"These things must be done delicately-- or you hurt the spell." - The Wicked Witch of the West.
"We've got the torpedo damage temporarily shored up, the fires out and soon will have the ship back on an even keel. But I would suggest, sir, that if you have to take any more torpedoes, you take 'em on the starboard side." Pops Healy, DCA USS Lexington.
