RE: Forming new brass question.
I would like to have a dime for every different fire forming method I have heard.
Ridge Runner and PA Wildman have it right(IMO). I am not sure about the recommendations about having to FL size new brass. I have shot a lot of new brass by just bumping down the neck(and making it concentric) with the expander ball out of the die. Then running a Sinclair sizing mandrel to open up the neck. I recommend this system, but I will admit thatthis iswhat I do to all my rifles, and I do not load my rifles hot, so headspace is never a problem for me.
Unless you are running a tight chamber the outside turning is not a necessity. You will get the most brass flow with your first firing. If you feel the need to turn, then I would turn it after your first firing, but I would want to know my chamber dimensions first. Tom.
