Why is (afaik) common ammo made out of lead instead of iron/steel?

Question

I thought lead is softer. Why is it considered better for ammunition?

Answer 1

There are several reasons.

For one, exactly, is more malleable. That means the production is easier.
It’s melting point is also relatively low. And the pouring can be done quite uniformly.

Also it’s more dense. More heavy at the same dimensions. That means it flies more accurate.

Another advantage is that BECAUSE OF it’s softness, it rips more fatal wounds. Where a bullet made of steel for example might just go straight through the body, retaining its shape, the softer lead bullet expands, widening the wound channel and damaging more internal stuff
