Hi,
I think I gave you quite a few solutions in another post but obviously your not satisfied with it.
So to make things clear:
You want to keep your sako with 308 boltface, right.
DON't Bother with a 302 whisper, if ssk does not want to export to you.
The 30 br is exactly the same , except for the lenght of the throat; you can have that adjusted with a throater or by having your 30br reamer throught ground for longer bullets.
The reloading dies are easy to find and the bullets are not to expensive.
Now for the 338br, what you are going to need is a reamer as well (I have one), some specific dies that are a bit more expensive and your are going to shoot a very expensive 338 grain bullet if you shoot the sierra match king 300gr.
It is your money, so i don't know what is your budget for the project, but if you can't afford to buy another rifle with a 223 bolt face to convert to 300whisper then your budget seems to be limited.
Then maybe stay with 308 winchester with a tight twist barrel like 1in 9 or 1in 8 inches and you will still have good fun up to 200m.Still the cheapest option then.
If you dont bother with paper work, you could ask your local gunsmith to remove your old barrel, and you can send your complete action to either Pac-nor in US or Border barrel in Scotland and have them rebarrel it to the caliber of your choice. Border barrel is not the cheapest option but might be the easiest regarding papaerwork: again a matter of money and time here.

I hope that with all that help you can make your mind...
good luck.
