Is that little spec at the bottom of the steel penetrator a bit of gun powder, or is it part of a steel tab that is left over on the core?


#3

Its part of a steel tab thats on the core, left over during the turning process. It was exactly in the center, and didn’t fall off when grinding so it was left on.
