I think it comes down to most folks put that larger wound channel into the lungs so they don't trash alot of meat which might not kill quite as fast as a bullet through the heart/arterial bundle that kills blood pressure really quick. I absolutely acknowledge a larger wound channel through the heart would result in a quick death too (and more margin of error on the shot), the meat loss associated isn't ideal though so pros/cons.If it works for you man, have at it. There's a place for them for sure. I've certainly dropped deer with both types of bullets but would put my money on the larger wound channel every time for the time to death calculation.
