Yesterday at a gun show I picked up some 9mm and .380 ammunition - Speer Gold Dot. It's not in a black box, it's in a gold box.
Both the 9mm 115 gr. GDHP and the .380 auto 90 gr. GDHP have a tiny "A" stamped on each primer. I've never seen this before.
The boxes look new and in perfect condition. Price was $30/50 rnds of 9mm, and $45/50 rnds of .380 auto.
There's nothing on the box to indicate that this ammunition is any different than the black box. It's Made In USA.
What's up? Being a gun show I have to wonder what it is I just purchased...
