Thread: Tikka 7mm-08 re-barrel to 7mm rem mag?

I have a suppressed, 18" barrel 7mm-08 tikka that I've pillar bedded into a boyds thumbhole stock and I really like it but since I will most likely end up moving down south I've been wondering if it could be re-barrelled for longer range.

So if I get a new barrel put on it and get one of the longer magazines will the action work as a 7mm rem mag? I guess .280 is the another option but I don't really want to get all the gear for reloading yet since I already have lots of stuff and not much storage.
