What can the .300 Win be converted to with a barrel swap?

[MASTEROFMALICE]

I'm picking up a Winchester 70 chambered in .300 Win Mag for a really good price. The problem (if you consider it a problem) is that I already have a Winchester 70 chambered in .300.

I'm considering tossing the barrel and rechambering it for something else. Now, due to case head similarities I'm pretty sure a .338 barrel would be a direct swap, right?

Question is, what else? What other calibers use the same bolt and OAL to make this caliber swap relatively painless?

Anything with a belt that's shorter than 375 H&h and bigger than 240 wby

It seems, from a brief bit of research that I'd be limited to either a .338 Win or a .458 Win, as these have the same rim diameter and such. Is this right or are there other cartridges I'm missing?

It would also be pretty easy to swap out the bolt to whatever case head diameter you wanted so in effect as long as it is a 'long action' cartridge it can be easily transfigured.
