Need explanation on why “stopping power” is seen as a myth?

I always hear people say if someone mentions “stopping power” they don’t know what they are talking about when it comes to guns. What is the definition of stopping power to you? This is the way I thought of it: We all know if someone is hit in any off switch area by a bullet they will go down most of the time but doesn’t the size of the finger pressing the button make a difference. If you barely miss the vitals with a .22 and you barely miss with a .50 BMG the results will be different. Thats a ridiculous example, I know, but it will be. Isn’t that an example of “stopping power”. I always assumed it had to do with wound channel size or something like that and not some reference to some weird magic caliber that is guaranteed to stop some one in a defensive situation. If all bullets stop someone if hit in the right area then why even use a bigger caliber than .22, apart from reliability issues. It is the easiest caliber to be accurate with with the right equipment.Leave the snarky comments to yourself. Im just working through a thought that I had. Im here to learn.Post description: Discussing what “stopping power” is in most people’s mind and why it is looked down upon as a pejorative in the CCW community. What is it? Why do people think its not real? Why do people choose the calibers they do, besides obvious platform size and ballistics? via /r/CCW https://ift.tt/3ulpqLW
