This is not correct. It’s common for modern ammunition to be jacketed with copper or some other metal, but the core is still lead (or lead-tin alloy) because it’s cheap, dense and soft enough to form into the rifling grooves while traveling down the barrel. Only special-purpose bullets are made with other metals.

Huh?

So do you just go on the Internet and make stuff up for fun?

Huh, that’s a new one for me. Who told you that?

Or was it pencils… So hard to remember…
