Yes, notice how it is shaped far more complicated than a normal lead bullet? Now why in the world would they make it so complicated if there didn't have to be a softer metal on the outside...? 🤔

Lead is 1000% cheaper than that style of bullet. The only way changing out all bullets to (functional) steel would work is if you wanted to make it even more of a yuppie hobby in the US...

Not to mention, such styles of ammo suck at dropping soft targets...
