Lead is denser, it weighs more per volume, so it travels farther and faster when propelled by an explosion. Uranium works even better, which is why they use depleted uranium in some military applications, as itâs more dense than lead, quite a bit better. Gold or platinum would work better too as they are heavier.
Fun fact, in a half billion years or so, the element of uranium decays into lead.
While thatâs a factor, itâs a very minor one - soft metals (lead and copper) are used as projectiles primarily because the bullet itself deforms to engage with the rifling when fired (softer materials also present far less wear on the rifling as a result - this is why shotguns, which are smoothbore and thus far less delicate, often use steel projectiles). The weight of the projectile is largely secondary to the mechanical properties of the material while itâs being fired.
