I bought 3 boxes of factory S&B for the brass. I was pretty disappointed.

Yep, agreed. Generally need a couple of firings b4 brass fully aligns with the shape of the chamber. Hornet though has thin walls.
What powder all you using and what velocity?

Looks OK blip.
What's the fine ring just back from the shoulder though?

I reload for 3 Hornets. The definite shoulder would solve the excess headspace on my 49 BRNO but I couldn't bring myself...
