Well bugger me, I'm pretty sure it shouldn't be that fast, but that was what I was getting on the crony, no errors or miss reads and a constant ES of around 20fps.
I did crimp firmly, but I'm guessing this is just a very fast barrel or Lil gun is a much better powder than I thought.

Accuracy, I didn't bother to measure but it groups in one ragged hole so it's pretty damn accurate.
