With a mold, bullets can be made at home for reloading ammunition, where local laws allow. Hand-casting, however, is only time- and cost-effective for solid lead bullets. Cast and jacketed bullets are also commercially available from numerous manufacturers for handloading and are most often more convenient than casting bullets from bulk or ...
A full metal jacket (FMJ) bullet is a small-arms projectile consisting of a soft core (often lead) encased in an outer shell ("jacket") of harder metal, such as gilding metal, cupronickel, or, less commonly, a steel alloy. A bullet jacket usually allows higher muzzle velocities than bare lead without depositing significant amounts of metal in ...
Cast bullets require a longer bearing surface than jacketed bullets to maintain an equivalent alignment with the bore of the firearm; because the softer cast bullet can be more readily deformed. The most successful cast bullet designs have a round or flattened nose rather than a long, unsupported ogive.
Lead-alloy bullets used with gunpowder firearms were unsatisfactory at the bullet velocities available from rifles loaded with nitrocellulose propellants such as cordite.By the late 19th century, lead-alloy bullets were being enclosed within a jacket of stronger mild steel or copper alloyed with nickel or zinc to reliably impart stabilizing rotation in rifled barrels.

Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration. [1]
The swaging process leaves an opening exposing the core on the base or nose of the bullet, while electroplating deposits a jacket over the entire bullet surface. Protecting the base of a lead-core bullet from burning powder gas may prevent molten lead from being released as a fine spray in turbulent gas leaving the muzzle of a firearm. [3]
The 7.62mm CETME had a lighter full-metal-jacketed, plastic-cored lead bullet with a reduced powder charge. While designing the CETME Modelo B and under recommendation of Heckler & Koch , the decision was made that the updated version of the original CETME Modelo A would chamber the more powerful 7.62×51mm NATO cartridge.
