I just got my American Rifleman and they have an article on this subject as well. Midway carries a lot of different barrels and if you want to convert from a 30-06 to a 300WSM you will need a new barrel, bolt or bolt face (both available from Midway), and some parts for the magazine. My brother-in-law has a .223rem Savage with a bent barrel, I might see if he would want to try this out, maybe convert it to .257 Roberts. For less then $200, you can't beat it.
