K=1/2mass x velocity squared. So velocity is very important. That fact alone is why we're interested in the little zippers at all. Now take a somewhat larger bullet, and get it almost as fast, and the permanent wound channel really takes off. I like a .45 185gr XTP round clocking about 1000 fps, and those .40S&W loads are good as well. 9mm is way easier to shoot and master, and it's big brother the .357 Sig is it's ultimate expression.
