Misinformation. One of the less harmful false notions floating around the internet is that no law enforcement agencies use frangible ammunition. This is false. The Federal Law Enforcement Training Center, United States Coast Guard and FBI, among others, use Sinterfire.

Why is frangible ammo illegal?

Secondly, because most frangible bullets are made of copper and/or an alloy, most are substantially lighter than lead bullets, therefore they may not strike to the same point-of-impact (POI) when fired from your firearm.

Are frangible bullets lethal?

A frangible bullet is very lethal to any unarmored target, no matter if they are a “good guy” or “bad guy”. Their dispersal quality just ensures that unwanted damage or injury is limited in the event of an errant shot.
