Sellier and Belloit is the only 9x18 I can find around here. I did get some Russian Silver Bear for my 82. Both shot just fine.

I buy most of mine on-line from AIM Surplus.
I bulged the barrel on my first 82 with a squib round of Silver Bear. I’m still a little leery of it.
However, considering the CZs were made to eat steel case stuff it’s nice to have the option if brass isn’t available.
