It's worse, its called cavitation. A high velocity

She explained that “the blast effect, or the cavitation effect” that a handgun shot causes is not as wide and devastating to internal organs as the one inflicted by high-velocity weapons such as the AR-15 and similar rifles. “When you see handguns, you often just see a little hole on the outside on both sides; shotguns, which are a little bit higher velocity, a little bit bigger. But assault weapons, it's much bigger,” she said, adding that as a bullet from this type of weapon penetrates the body, it typically creates a large cavity that can cause significant bleeding from vessels and completely destroy soft tissue, as well as organs.
“The organs, for example, like the liver or the spleen, that aren't very elastic, they can't handle that. They would basically rupture,” Naik-Mathuria said.
She added that the reason the AR-15 is so deadly is that victims are hit by more than one bullet, with multiple injuries at a time.
