"達姆彈" = "dum dum bullets." It's nothing more than an old term describing bullets that "expands" upon impact. In the old days, this means softer lead point. This evolves into "hollow points" to aid expansion upon impact.
In modern days, the term "dum dum" is no longer used. We use the modern term "hollowpoint," which basically achieves the same thing. And yes, the Hague Convention does ban modern hollowpoint bullets, eventhough the name "hollowpoint" was not specifically used. Hague Convention bans bullets that are "designed to expand" upon impact.
Hollowpoint is very, very commonly used by police and self-defense gun owners in the U.S. Yes, hollowpoint bullets causes more damage upon impact because of the expansion. However, the more important reason to use hollowpoint bullets is public safety. Full Metal Jacket bullets tend to over-penetrate when impacting human bodies. This means, if police shoots a bad guy with FMJ, our bullets may go through and exit the bad guy's body and hit another innocent bystander down range. By expanding upon impact, hollowpoints tend to stay in the body after impact. So, it's safer for innocent bystanders.
We (police in the U.S.) are mandated to carry hollowpoint bullets in our service weapons, including our off-duty guns.
