What type of bullet is known for its expanding capabilities upon impact?

The jacketed hollow point bullet is widely recognized for its expanding capabilities upon impact. The design of this bullet features a hollowed-out shape at the tip, which allows it to expand when it strikes a target. This expansion increases the bullet's diameter as it penetrates, leading to a larger wound channel and more effective energy transfer to the target.

The jacket surrounding the lead core provides structural integrity during the initial stages of flight and impact, ensuring that the bullet maintains its shape while allowing the lead tip to expand quickly upon hitting the target. This combination of features is particularly valued in self-defense and law enforcement situations, where stopping power is crucial.

While other types of bullets may have some degree of expansion or expansion characteristics, the jacketed hollow point is specifically engineered for this purpose, making it the preferred choice for maximizing effectiveness in defensive scenarios.
