"Dum Dum" comes from the name of a British Raj (colonial) arsenal near Calcutta India, they issued these "Xed" cut LEAD bullets because they want a little extra lethality (and during the Sepoy rebellion in 1857, they needed it)for their troops who were outnumbered about 1000 to 1 by the rebeling "native" troops. The "native" troops, a combination of Hindu,(vegetarian) and Moslem (no pork, please!), were p*ssed off because their cartridges were lubricated with animal fat, probably sheep, but maybe pork. they went on a rampage and slaughtered every "white" man woman and child they could find, it took some time for the Brits to put the whole thing down. When the Brits captured the rebels, the normal punishment was to strap them over the business end of a canon barrel and fire a ball or grapeshot through them. The Brits weren't quite as politically correct then.
Dum-Dum bullets were eventually outlawed by the "rules" of war treaties in the early 20th century, and being caught with them was a death sentence. Cutting a jacketed bullet will have little effect unless the jacket is very thin and a lot of soft lead is exposed.
