"Stamped on the box" I assume?
It was the proper dimensions for the .380 cartridge, correct?
It’s been a long time and I can no longer remember the details. The bullets fired just fine.
Thinking about how the stamping must work, I can’t believe it was entirely clear. One of the guys said, “Hey, it’s stamped 9mm Luger.” Until recently, I haven’t had any fine detail in my vision due to a variety of eye problems.
