Intro to Gun Calibers - Which Ammunition Does What?

It's time to give a quick but detailed initial overview of what pistol, rifle, and shotgun calibers of ammunition do, don't do, and when and where you'd most commonly use them. This video focuses on defensive use and hunting use fairly equally since those are the two major uses for firearms. I also give some advice for which style of firearm to get if you're totally new to the gun scene.
