Make sure your components are in a safe place!
This is what happens when a whole box of Federal Pistol primers go bang.
He is a dearest friend of mine, a very experienced reloader and safe as anybody can be, but shit will happen to anybody at any time. According to the story, he was in his shop grinding some metal but did not realize a box of primers was where it was not supposed to be. He was wearing eye protection which saved his sight as he tells it “they were destroyed!”
Don’t worry, I will give him all kinds of hell when I see him.
