Not very often does Hollywood get anything gun related correct, but they sure did in that movie with Kevin Costner titled "JFK".....The Italian Carcano, just as they said in the movie, "has to be the worst shoulder fired weapon ever made"...If you have ever handled one that is bad enough, but to actually fire one and then think about the actual shooting that was {I guess} done that day....I gotta agree, "the guy couldn't do the shooting" I mean, in reality the idea someone, anyone, did that shooting with that rifle....honestly makes the so-called "magic bullet theory" seem entirely plausible.
I guess you are looking for more modern stuff, but I am just surprised that nobody mentioned this rifle on this thread up until now.
