Bullet
The Jacketed Hollow Point (JHP) has a lead center (core) with lead showing at the tip.  It also has a strong metal coating (jacket). The center of the tip has a hole in it (hollow point).  This design makes the tip of the JHP quickly start to spread out (expand) when it hits a target. The hollow point bullet in a rifle can be as small as a pin. When the hollow point is this small, the bullet will go faster and still spread out when it hits a living target. In some hollow point rifle bullets, the front may spread out to two times as wide as the bullet was when it started. It is a good hunting bullet because the energy in the bullet is transferred to the target at a known depth.  The jacketed hollow point tends to be accurate and is sturdy.
