What business does Business Insider have pitting an AK-47 against a Smith & Wesson .50 cal in outer space? That would be like TTAG comparing the effects of Adam Smith and Karl Marx in outer space. That said, it’s good — if not surprising — to know that .50 S&W generates more kick than Mr. Kalashnikov’s fabled long gun. The .50 producing a not-entirely-impressive 1.36mph in rearward travel. Enough to cover a football field in 30 minutes! Sounds like the Texans football team to me. Sounds like “guns are dangerous” to BI. No surprise there, either.
