hollowpoint bullet 

Bullets with a cavity in the tip to allow greater expansion and less penetration on impact with a target.

Usually identified as "cop-killer bullets," even though hollowpoints are actually less effective at penetrating body armor than standard ball rounds.

Homeowner: I use hollowpoint bullets in my home defense firearm so I don't risk injuring an innocent bystander.

target, causing maximal damage. Hollowpoint bullet easily
takes someone's head off. Hollowpoint bullets are illegal in
most countries for civilian people.

Did you see that police shooting those hollowpoint bullets to
