True, but the alternative is tungsten, which is not much better in terms of toxicity: https://www.atsdr.cdc.gov/toxprofiles/tp186.pdf https://www.atsdr.cdc.gov/toxprofiles/tp186.pdf The problem here is that armor piercing rounds need to be made of heavy metals in order to work and heavy metals are generally toxic.
