Rifle is a impact precision with hawk hill 6bra barrel chambered by Hawk Hill.
Dies are custom.
When I tried to size the first fire formed brass I couldn’t bump the shoulders at all. The dies would contact the shell holder. When I called whidden they said to take a little off the base of the die. While I’m not crazy about doing this to expensive dies I do have a shooting buddy that has a machine shop. I had him take 20 thou off the base of the die. Now That I can bump the shoulder it looks more like a 6br then the modified 6bra. Unfortunately I didn’t notice the visual difference after sizing. I only checked how far the shoulder was being bumped. Since the tool goes from the center of the taper it seemed good. I didn’t notice the problem till the load I worked up with the fire formed brass was popping primers.. In the picture the brass on the left is a factory new 6br. The middle is a fire formed 6bra. The one on the right is a fire formed case sized with the whidden 6brai die. I’m awaiting response from die maker. In the mean time I may contact Wilson to see if they make a 6bra die. I just started loading for my 338 lapua with one of their dies and it shoots incredible.
