The first Pulitzer prizes are awarded
Al Capone is scarred in a knife fight, thus the name “Scarface”
French soldiers mutiny, thus earning the French army the reputation of being cowardly
The draft for WWI soldiers begins
And 100 years ago this ammunition rolled off the line!

I was contemplating on what to do with the old ammo that I dissected.
It's easy to put it back together and try shoot it.
It would be cool to have a m1917 revolver to do that.
Even though the primer is corrosive, I doubt that one round would deposit enough salt to damage any gun.

Maybe next week I'll take apart a round from 1932. Lots of interesting things happened in 1932.
Depression, gangsters, infamous bank robbers

Cordite powder?

Yep thats cordlite

This is interesting.  I have green boxed Remington 45 acp from the 60s I believe.  I ran a few mags of it at the range once I looked it over.  It was a little weak, but still cycled my firearm

if it's boxed, might be worth some money.  vintage ammo to go with a vintage 1911
