I stumbled across this and found it really interesting.

I am really amazed that almost everything in common use today was developed over 50 years ago and many of them 70+. I've recently gotten into milsurp rifles and to learn that those cartridges were developed over 100 years ago really amazed me. They still shoot great. Anyway, I just thought I'd share.
