Remember the tons of Swedish black plastic bullet short range cartridge with the steel ball in the tip that came into the US 5 or 6 years ago. Well, it looks like a little company in the Czech Republic found something to do with them.
The company is Limit-Z s.r.o in Luhacovice, Czech Republic. Apparently they reloaded a bunch of the Swedish ammo as ball loads, and marked the side with a stamp that says “9x19 LZ” to comply with EU rules that commercial ammo must be marked with the maker and the caliber. This packet showed up in Holland. I haven’t seen any other packets. The headstamps are all Swedish post WWII, mostly from the 50s & 60s but some as late as 1983. One was a commercial Norma headstamp. There is still a residue of the blue case mouth seal on the cases.
