I actually bought the brass in order to form it into 35 Newton but, when it showed up, I was just plain smitten by the cartridge so I put it aside. I since made the Newtons out of .375 Ruger (when it was easily available).

For your brass, do you fire and push the case out to the belt diameter? I looked into that for the .280 Ross but decided not to head that way. I've heard differing opinions on what that does to case life.
