The original story for this must have been edited. I read the story, and it referred to "a rifle."
The magazine being a one time use reminds me of the chuckle I received at the expense of Rob Leatham. He told the story in public, so I can feel ok about repeating here (Ok ok, I don't care about where he told the story, because it is funny, at his expense, and I like it). When Rob started shooting revolver a few years back, he didn't know that moon clips were reusable. He gets them free from his sponsors. The guys following him picking up brass loved it until he found out this little fact.
