Possum, you can take a great shooting rifle and re-barrel it to another caliber then put it back exactly how it was and it still shoots excellent. I was very apprehensive about taking my .243 apart but it was a 22-250 AI for a while and is now a .243 again. A barrel can be had from Midway for $129 and is just as good as your gun has on it now, probably finished a bit better.
