Today, I spent the afternoon translating Korean text into English in a book chapter about black powder (very interesting reading that will be very useful in my dissertation). While flipping through the rest of that chapter, which is on Korean Joseon dynasty guns of all sizes, I ran across the mention of one peculiar piece. It was an extra-long smoothbore matchlock: 65" overall length with an approximate 51" barrel (and weighed in at 22 pounds). There is an even longer example in a museum in Incheon with a 68" overall length and approximate 53" barrel (and .91 caliber). They were recorded as shooting 1,000 paces (over 3/4 of a mile). Was there anything comparable during the same time period (~18th and 19th centuries) in the West?
