No matter what people (including John Cooper) say, being shot with a full-tilt (read 800+fps) .25 ACP 50-grain FMJ to the head can prove fatal. JMB engineered it to replicate the .22 Long Rifle from a 2-inch barrel.
It may not be optimal, but I wouldn't volunteer to be a "test dummy" to test its short-range efficacy.
