They have identical performance. It's just a matter of which one you prefer to use. I find lead more handy because it's cheap and works fine.
Mild steel
twelve pounds of Steel is more because it's density is less than Lead.
Lead. Lead is denser so it has a higher ballistic coefficient. This may sound like gibberish but to explain, because the lead is heavier by volume than steel it is "heavier" vs. it's diameter, in other words for the same size shot it has more weight which will do two things. Lead will maintain it's velocity farther down range because the steel has more wind resistance. And because lead "weighs" more and is traveling faster downrange, it will penetrate the target more.
Radioactive elements are unstable, and the shorter the half-life, the more unstable they are.
density is a physical property of the material, it has nothing to do with the size of the piece. lead is 11.35 g/cc iron is 7.874 g/cc steel is between 7.75 and 8.05 depending upon type of steel.
what is the only way air can become unstable
Not all isotopes are unstable. But now more than 3 000 unstable isotopes are known, artificial or natural.
Any atoms that are higher on the atomic scale. Elements that have a higher atomic number tend to be more unstable. Lead has the number of 82 and it is considered to be the most stable element.
I just sold 3 of them for $ 12.36. UncirculatedMoreThey're not lead. They're made of steel and the only zinc is a thin coating to protect the steel from rust. Circulated ones are worth much less - please see the Related Question for more information.

1 kg of water. Water is less dense than lead. This means that the same volume of water will be lighter than the same volume of lead. Reversing this, 1kg of water will have a larger volume than 1kg of lead.
