since you are changing out the barrel any cartriage with the same rim size should work i.e. 22-250, 250-300, 257 roberts, 25-06, 35 whelen , 338-06, and on and on. Check with a good gunsmith before starting some thimes its easier to have them start fresh and build a new rifle.

What are the intended uses?
It all comes down to the intended uses.
If it will be for more of what you were doing before, it's really hard to come up with something as versatile as the 30-06.
Changing to a shorter (308, 250-3000, 257 Rbts) cartridge can give you problems with the length of the magazine and the shape of the mag follower and the feed rails. Keeping to a cartridge of the same basic length and shape make things easier.
This means stuff like 25-06, 6.5-06, 270Win, 280Rem (7mm-06), 338-06, 35 Whelen, and then some serious wildcats that are just plain wicked.
Don't count out all the Ackley Improved type cartridges either.
Me personnally? I'd opt for the 35 Whelen.

The feed rails on that action can be pretty critical when changing calibers, for a reason that might not be obvious. If you partially chamber a round and don't close the bolt fully, the extractor will not engage. If you then operate the bolt and pick up a round from the magazine, its bullet point will be aimed close to the primer of the round in the chamber. The factory feed rail angle is calculated to keep that bullet point away from the primer, but if another caliber is involved, the situation may change.
Be assured that if you hit the bolt handle and jam a spire point into the primer of a chambered round, nasty things will happen very soon thereafter.
(That, not "jam prevention" is the reason Mauser went to so-called "controlled feed" when bullets became jacketed and more pointed.)
