OK…here is my suggestion…
Get you a darn good rifle shipping box and ship it to a qualified gunsmith with a defined track record. I bet you could look on this sight and find some talented gentlemen (women maybe) that do this stuff for a profession. Save your gas money...
I am not trying to spend your money, but loose the "great price" or WalMart shopping ideas. You will get what you paid for and quickly learn that your rifle shoots stinky groups and that is the best it is going to get. If you want to reverse it, you have to start all over with another barrel and most likely another gunsmith. The "pros" know close to what the barrel will do with your action, etc., or pretty darn close when they take it apart.
Look on this website or try Varmint Hunters magazine or Presision Shooting magazine for gunsmiths. The guys that mechanic for the competitors have an established reputation and do quality work. They are darn good/great so they don't work for a six-pack of Milwaulkee Best.
Find a gunsmith that you can communicate with, understands what you want in a new barrel, what you want to use it for, listen to his/her recommendations, do some research so you know what he is recommending and ship it off to him.
Now, after purchasing a Pelican case, I ship my rifles to Powers, Oregon from Texas…and I have not one gripe on his work. OK, maybe one...it's not free.
Gotta go...buy some socks at WalMart...my last four pairs have worn out.
Good luck!
