I'd say it depends on what kind of reloading you're doing. At 2200 fps and 286 gr bullets, my Zastava Mauser is fun to shoot. But that extra 200 fps...
Given powders like 2000-MR and Big Game and RL17 (maybe RL15), 2500+ fps and 286 or 300 gr bullets is on the table. 2600+ is do-able for 250 gr pills. The actions are perfectly capable of handling that, but they aren't as heavy as 375s. I'm going to have maybe 10-12 ozs added to my Zastava this fall or winter, plus a Limbsaver or Pachmeyer. I'm not worried about the field, but load development is challenging, given these possibilities. With my current setup, 20-25 rds is my limit for a day. I know that isn't 416 territory, but it is a consideration.
If you're happy at 2250-2300, 8 1/2 lbs should be fine. If you want to push it, well, it sort of depends on how recoil-sensitive you are. Shoot a light-weight 338 WM pushing 250 gr at 2600 +/-. Same thing.
All that, I wouldn't trade my 9.3 for anything.
