Home defense ballistics always come up when you talk about shooting in a building. Is a pistol better than a rifle? Is birdshot better than buckshot? The questions (and arguments) go on and on.
We found a great video that shows you what exactly happens when you shoot. It isn't going to end the arguments, but it will give you a good basis to talk from.
Take a look at the video and let us know in the comments what you think or have experienced.
