A fancy way of saying a jacketed round. Jackets are thin layers of metal (usually copper) which coat the actual bullet itself, providing a smoother surface to both streamline the bullet, and reduce the chance of breakage in the barrel or in flight, as lead is a soft metal, and easily deforms.

The shell around a bullet, commonly referred to as the bullet jacket, is typically made of copper or a copper alloy. This metal jacket encases the lead core of the bullet, providing structural integrity, reducing barrel fouling, and improving aerodynamic performance. In some cases, bullets may have jackets made of other materials, such as brass or even polymer, depending on their intended use.

The copper jacket is needed to push bullets at very high speeds and to withstand the very high rpms generated by the rifling. A lead bullet would fly apart because it is too soft. The harder copper jacket keeps the bullet in one piece.
Jacketed hollow point.
A bullet with a full metal jacket has a tendency to ricochet pretty hard after hitting the targets. This is why at most indoor and outdoor ranges bullets with full metal jackets are banned.
