Are depleted uranium bullets a real thing?

Depleted uranium bullets are a thing, but they're not as exciting as they sound. Depleted uranium is a byproduct of nuclear power plants, and it's used in everything from aircraft counterweights to radiation shielding.

It's also incredibly dense, which makes it ideal for use in armor-piercing ammunition. In fact, depleted uranium bullets were first developed for use by the military in the 1970s. However, they were never widely adopted due to concerns about potential health risks. Today, depleted uranium bullets are still used by some militaries, but their use is controversial.
