A hollow-point bullet is a type of expanding bullet which expands on impact with a soft target, transferring more or all of the projectile's energy into the target over a shorter distance. Hollow-point bullets are used for controlled penetration, where overpenetration could cause collateral damage (such as aboard an aircraft ).

2019年11月2日 · Hollow-point ammunition contains a divot in the very tip of the bullet. Upon impact with soft materials — such as flesh — the material fills this cavity and causes the surrounding rim to mushroom out.

2016年7月15日 · My professional relationship with hollow-point handgun bullets began when the Dallas Crime Lab started getting questions about them in 1971. There were many myths and misconceptions running amok, and some persist today. I thought some information I've learned over the years might be useful.

The stopping power of a 9mm hollow point bullet comes from its ability to expand and transfer energy effectively into the target. When the bullet is driven into the target, the hollow point causes it to spread out, or “mushroom,” which increases the size of the wound cavity and helps prevent the bullet from over-penetrating.

Jacketed hollow point (JHP) ammunition is designed to uniformly expand (AKA “mushroom”) on impact. It’s easy to spot because the top end of the bullet is, you guessed it, hollow. This clever expanding design allows the bullet to do three things really well:

Most hollow point bullets feature meticulously engineered profiles, so their copper jacket material will peel back and allow the lead core to bulge into a mushroom shape. This results in uniform expansion, making the bullet’s terminal performance predictable in a variety of target mediums.

Hollow point bullets were designed to "mushroom" as soon as they hit a soft target. They were specifically designed to create a large wound cavity in order to incapacitate a target quickly. Because of their potential lethal capabilities, use them with extreme caution.

2024年5月20日 · Hollow Points (HP): Probably the most common type of expanding bullet. Hollow point bullets have lines and perforations carved into the projectile itself. When these projectiles hit a target, the bullet tears along those perforations like a piece of notebook paper. That causes a hollow point to (as Caleb says) “spread open like a beautiful ...

2023年12月6日 · Explore the world of 9mm Jacketed Hollow Point (JHP) ammunition, its design, benefits, and potential drawbacks. Learn about flowering or mushrooming, a critical aspect of JHP bullets for enhanced stopping power in self-defense scenarios.

2019年9月20日 · A hollow-point bullet is the type of ammunition that has a hollow tip with a cavity cut into it. The bullet is manufactured like this so that when it passes through soft tissue material, the pressure created within the pit of the cavity will force the bullet to expand outwards creating a mushroom effect.
