Jacketed Hollow PointsĪs you shop for ammo, you might come across jacketed hollow point (JHP) rounds, which are an advanced (and pricier) version of standard HP. You are allowed to have them at home, though. The one exception is New Jersey, which has made it illegal to carry HP rounds in a concealed weapon. But the complex design of HP rounds makes them more expensive to produce.ĭespite efforts to enact controls, HP rounds are legal to own and carry in every US state. As a result of this design, HP rounds tend to get lodged in targets and cause more catastrophic damage. Also called “mushrooming,” this design ensures that all of the bullet’s energy is deposited in the target. Hollow Point is a type of bullet made with a pitted or “hollow” tip, which is designed to expand upon entering a target. The simple design of FMJ rounds makes them cheaper to produce, which means you can get more ammo for your money. This design helps the bullet retain its shape, energy, and velocity when it passes through a target. Case – the shell that holds the whole package togetherįull Metal Jacket is a type of bullet made from a soft lead core that is “jacketed” (or covered) in a sealed shell of harder metal.Primer – the explosive catalyst that ignites the powder when struck by the hammer.Powder – the explosive substance inside the case that propels the bullet out of the barrel.Bullet – the projectile that flies out of the gun when fired.While we tend to call cartridges “bullets,” the bullet is technically only one part of the cartridge. “Cartridges” or “rounds” is how we refer to firearm ammo.Ī firearm cartridge is actually a four-part ammo system combined in a single package. Arrows are ammo for bows, rocks are ammo for slingshots, and cannonballs are ammo for cannons. The word ammunition (or ammo) describes the projectile system for a weapon. Let’s take a look at both ammo types to see how they work and their advantages in a home defense scenario. Just as you need both a hammer and a wrench, a responsible gun owner needs both FMJ and HP rounds in their toolbox. FMJ and HP rounds each have unique characteristics that make them better suited for specific situations. But the results will probably be suboptimal. If you try to use a wrench as a hammer (we’ve all done it), you might succeed. A hammer is not better than a wrench, but a hammer is better at hammering and a wrench is better at wrenching. Like any tool, you have to pick the right one for the job. To understand the difference, it’s important to remember that despite the purpose or cultural significance, firearms and ammunition are just tools. The most common choice is between Full Metal Jacket (FMJ) and Hollow Point (HP) rounds. ![]() If you recently bought your first firearm, the next obvious question is: what about ammunition? As you browse the online store of your favorite ammo supplier, you’ll notice a wide array of ammunition types available. If you want to be prepared, the most effective self-defense tool available is a firearm. While statistically unlikely, you never know when it could happen to you. One of the most terrifying situations someone can be in is a life-and-death struggle. ![]()
