I was going through some of my old files recently and came across this article from a 1958 issue of The American Rifleman. I scanned it, but to keep the file size low enough to post it here, it became nearly unreadable. It can still be read, though, so I'm attaching it for those who may be interested. I should say, though, that there is no real new information for most of us. I still thought that it was interesting.
