At the Czech Meeting the guy who runs ZVS confirmed to me that he was making HotShot headstamped ammunition for Century (packed in HotShot boxes), as well as selling ZVS ammo in the US. Unfortunately, he put most of his ammo, including his HotShot ammo in his car the day before the meeting and then drove the wrong car to the meeting early the next morning and left most of his ammo at home.
At least, that is what I think he said. He understands some English and speaks a little English. Our conversations are always through a third party and I’d guess my comprehension is about 80% or 90% accurate, but could be 50% for all I truly know. It could be he really was saying that he was selling his ZVS ammo to Century. However, as I mentioned on page 1 of this thread, I was previously told by a Slovak collector who knows the head of ZVS quite well that they were producing HotShot 9mmP with the HotShot headstamp.
I hope to see him again in the Spring, but for now can only keep a lookout for brass case ammo in HotShot boxes.
