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.




I was told that I could make 30 Newton brass by fireforming 300 Win Mag brass. I did that but was concerned about the brass strength at the head. It seems that the brass would be very weak where folded out at the belt ant immediately bend 90 degrees where it hit the chamber wall. I used that brass for only mild loads. Luckily I found some Speer brass and then Jamison made 30 & 256 Newton brass.
