With so many people buying up firearms and ammunition like it's 2012 again, I got to thinking about just how many people there are that are buying/own ammunition/firearms that they know little or NOTHING about. For example, one time I was at my local gun shop and overheard this guy tell his buddy (with the utmost sincerity), "Naw man, 9mm Luger is way more powerful than 9 x 19 Parabellum." I waited around to hear a snicker or some indication that he was just messing with his friend, but began to realize that this guy really believed this. What's some of the crazy, misinformed BS have you guys heard from people regarding firearms, ammunition, hunting, shooting, etc.?
