FMJ

A Full Metal Jacket, or FMJ, is by far the most common bullet type. Common design has a copper jacket encasing a large lead core. This bullet type rather deforms depending on point of impact and obstructions, rather than expands ("mushrooming").

This and it's fair performance against both flesh and armor make it a popular choice with gunslingers.
