I rang every gunshop I could think of just a few days back from the tropic of capricorn to the southern ocean - no Swiss - Wano or wano or Wano - just would have liked a can of Swiss to test
Have not seen Goex since 1995 but still have some of that left (Moosic Plant powder from before the blowup) its way better powder than any wano I have had - Aussie shooters filled the gap with Chinese fireworks powder for a good number of years -- I had some of that ages ago that was as good as the best ever for clean burn - later was dirty powder.
