The article was interesting. Noticed this about French ammunition.

"The reason is that the original Berdan-primed cartridges were madewith a specially scored internal annular groove between the head and body to purposely weaken the case and preventreloading by enemy forces, which had apparently been a problem at one time for the French when they occupiedMorocco."

I love it when countries try to booby trap their shit, so someone won't follow on behind them and use it against them. Read an article once about ammunition that was designed to explode, and it was planted by US Forces in Viet Nam. Been a long time, so don't recall any details. Just shit designed to fuck up your day if you stumble upon it.
