I once saw a guy who had been shot with a "reverse" wadcutter. He pulled a .22 and fired one bad shot at an investigator who returned fire with a S&W model 38 loaded with them. The guy was hit from about 30" and the round went through his heart. The perp never got off another shot nor did the investigator need another shot. That old mod 38 became mine several years later and is in need of a serious reblue as I've carried it off and on for over 40 years and a lot of the finish is worn off of it. My friend Leland loaded me several of the backward wadcutters and I have several house guns loaded with them.
