Ok, so its possible to rebarrel to a 308, though the receiver probably wouldn't be able to handle the pressure. The other option comes down to handloading, which I suspected would be the case anyway. I've toyed with the idea of handloading for awhile and I have a family friend who has everything I need to do it I believe. This I think may be the right way to go, as nice as it would be to just use a standard 308 out of the box, it's probably not too safe it sounds.

One book I have on the subject says that I should use .303 cal bullets if I reload but also says that the .308 will work, but can cause the grooves to wear out faster. Have you experienced this at all? Have you tried .303 bullets at all?

Thanks for the response eldeguello
