Yes, I understood what you meant with this. Now how about a 20mm cannon round? That should be able to impart some serious physical stopping power. Seriously, we don't carry 20mm cannons in our holsters so that is not a consideration. What we are concerned about is those more popular handgun calibers and loads that have developed a good track record of doing what needs to be done when a victim's well being is on the line. If stopping power is to be the term that we use to relate how well a given caliber and load performs, then so be it. I can go with that. As long as there is some sort of definition which is acceptable and understood by people then that's what it will be. Sanow and Marshall came up with a definition of "one shot stops" they used in their three "Stopping Power" books in the 90's and early 2000's. Don't know if that is still used but I like the idea that if you fire upon someone and they cease their violent attack on you, then some form of stopping power existed. Whether they succumb to their wounds is irrelevant. What is relevant is the fact that they were stopped from continuing their assault. I can live with that.
