A "hollow point" is a type of bullet designed with a hollowed-out shape at its tip. This design allows the bullet to expand upon impact, creating a larger wound channel. The primary purpose of hollow point bullets is to increase stopping power while minimizing the risk of over-penetration, which can be dangerous in populated areas. Hollow point bullets are commonly used in handguns for self-defense and law enforcement. They are also popular among hunters because their expansion can lead to a quicker, more humane kill by transferring more energy to the target.
