With my little cousin we did some metal detecting, in the hope to find some nice old coins.
No coins where found, but we did find a big bullet.
In this field I found previously several the same bullets as well as casing of it.
I offered him to clean up the bullet, and drill a hole in it, so he could wear it on a chain around his neck.
At this point I tried to drill a hole in it, but it was not possible. With my best drill bits at the slowest speed, I could not even get a dent in it.
Being curious what this bullet was made of, I decided to cut it open in the length with my angle grinder.
I started at the back, working my way to the tip.
Almost at the tip, it started suddenly flashing with bright sparks, so I quickly moved away.
When it was done “flashing”, and my tool shed was aired, I checked what happened.
He did some searching and found that this means it was made in St. Louis, in 1944, therefore used by the US air-force when they where firing at the Germans during WWII.
It turns out that this was a API round, Armour Piercing Incendiary.
The white phosphor in the tip is dangerous stuff, I was quite lucky nothing serious happened.
Moral of the story is, don’t cut old ammunition open, unless you know 100% what it is.
More information on the round itself and the casing can be found here:
