Had a neighbor who after enough beer would light his farts however he always did it bare arsed, doubt it would have blown a hole but holy crap it was entertaining.

I heard the cows are very gaseous! Anybody want to try that in an enclosed barn? Maybe that is how the Great Chicago Fire started

Possibly Mrs O'Leary was having some fun?

Some feed back on a more serious note. Apparently the kortnek blow-ups is not a myth. Apparently what would happen on occasion was the bullet would upset in the unsupported neck area then on swaging into the throat the core would get blown out leaving the jacket lodged in the throat. The following round would chamber but developed high enough pressure to blow out the breach. It has been recorded that some Boers refused to use the kortnek.

Now getting into uncharted territory, the alleged solution was to apply a bullet lube to the exposed bullet which would support the bullet in the neck and prevent these occurrences. Apparently there is a report of the British executing a group of captured Boers because they thought that the 'brown stuff' on the bullets was a biological substance which caused wound infection. ??? I haven't read the sources to confirm this but I have at least found the sources. It will be a while before I get around to reading all that material!

I do not know if this is related or not - but I was doing some research on some 7x57mm cartridges and chargers (clips) from the mid 1890's. I though they may have been used in the Spanish-American War of 1898. I came across some data that stated Germany also used some 7,65mm Mauser cartridges formed into 7x57mm during the Boer War period, These would have a shorter case length and a shorter neck, nothing was stated about any problems using these reformed cartridges

The Spanish did use the 7x57 Mauser in the SpAm War, and the 7mm "Kortnek" rounds were indeed made from available 7.65 Mauser cases.
