7mm rem mag brass to 264 win mag?

[.284]

Is this something that can be done by running the 7 mag brass through a 264 win mag die? Seems to be doable to me but I was hoping someone would know for sure
Thanks

Yes, same case. 7mm Rem Mag was made from 264 Win Mag by Remington.
I use them to make 257 WBY brass.

x2 I re-size to 257 weatherby also but use new brass only, you may have issues with used brass.

I know, I only use new brass to fireform, I just got my hands on 5 boxes of new WBY brass for $ 30 each so I don't have to anymore
