Case capacity pretty close. 7RM psi is capped by SAAMI, is lower than 7WBY. There have been long discussions why. Running at equal pressure, not that much difference.

Yes, and I'm sure that you know that the Wby freebore is definitely part of the discussion.
edit: sorry, M D was just a little quicker typing than I.

Yep
JB was pretty quick.
My smith thought the 7RM was potentially more accurate than the Wby. Now, that should open a can of worms.
In fairness to the Wby, if it’s carefully chambered with a tight freebore, accuracy can be excellent.
I went with the smith’s suggestion; he’s sort of an accuracy nut. I have no regrets.
