I know of someone with a 30" barrel chambered in 7WSM that is getting over 3000 fps with 180gn Bergers so I would think that a 7mm Rem Mag and a 32" barrel could do better.
I have a 30" plus a muzzle brake. During pressure check load development I was approaching 3000 with the Berger 180VLD and stopped there. Final load was reduced with a velocity near 2800 producing best precision and ES. The higher charge loads were all around 1 MOA with high ES. Not good for what I was after. I don't believe I would have seen any advantage with anything over 30" in my 7 Mag. Just my $.02 and I'm sure there are others achieving higher velocities over 3000 with good results.
