7mm BR Brass
- Thread starter 6XC243
- Start date
Remington was the only maker that I know of and they discontinued it years ago.
You could maybe find old Remington NOS but it would be expensive and silly.
6mm br brass and some elbow work is the easiest option.

Thanks steel head! I was afraid of that. Now I know why that xp was so cheap! I guess I could make a 22-250 out of it. Or sacrifice some of my 6 creedmore, although all of that has been going to the PRS matches.?
Oops! I thought you said creedmore ( face palm) you said 6 BR! I supose I could do that. Thanks again.
An expander die with 257, 264 and 284 then run is through a standard die and your golden
May need to trim and because your turning shoulder into neck with lapua or Norma brass you may get a donut which Depending on throat and bullet may warrant neck turning.

Thanks for that info! If you have time, explain the term "donut". I was under the impression it was a term that had to do with the bore in the barrel.

On a lot of brass the shoulder is thicker than the neck.
When you turn shoulder into neck now your neck is two thicknesses with a thick spot at the shoulder neck junction.
You can actually feel it when seating a bullet if your seating bullets deeper than the base of the neck.
I have definitely seen it affect extreme spreads in velocity.

It makes a tight spot in the neck.
Make seating pressure and grip inconsistent.
If you had a super tight benchrest chamber with tight neck it could cause pressure issues.
That makes sense. Would the same pressure variance come about when the brass is too long?
