I typically carry ammunition that is a bit warmer then most here but it's not because I believe it will stop an assailant faster than standard 9-45 service jhp loads but because I don't think they will be worse and I have bear and moose in my back yard. 170gr swc @1200fps or 255gr swc @ 950fps gets me to where I think I want to be. So far the coyotes drop faster with blood and bone sprayed farther than when using standard 9-45 jhps.
