This video uses the data from Greg Ellifritz's 10-year stopping power study of real-world gun fights to shed the light of actual data on several common beliefs about handgun calibers including: 22 rifles are the best bug out guns, 45s have the best stopping power, 380s are too small to be effective, 410 guns are gimmicks, and more.
Here is the link to the original data and study by Ellifritz:
