Disadvantages
There are some disadvantages to jacketing a bullet. For instance, full metal jacket bullets have different properties, both in terms of behavior inside the barrel of the gun and also in flight. Whereas hollow point and soft-tipped bullets are designed to expand upon impact, full metal jacket bullets are limited in their capacity to expand. This makes the bullet pierce through, in many cases leading to decreased target damage. Hollow point and soft tipped bullets are for use against soft targets only, such as animals or people, whereas full metal jacketed bullets can be indiscriminately used against soft and hard targets, delivering sub-optimal damage to both kinds of targets. Jacketed bullets require a certain velocity for proper expansion based on their size, and a larger quantity of gunpowder must be used.
