6mm XC or 6X47 Lapua

Any of you gunsmiths out there know if it would be possible to rechamber a factory .243 sporter barrel to 6mm XC or 6X47 by turning it back the needed ammount and rechambering for one of the above? I have quite a few parts left over from my Savage builds and would like to build something like this a a low $$$ build for a knock around gun to carry in the truck and ATV.
If this would be possible could anyone suggest a smith that could do this as there are not any around me that I am aware of that could do this. Thanks All

I recall just seeing that offered on a site today, i want to say it ran around $125.00 , but i'm not sure...Found it.!!! it is SSS but from what i hear, he has been real busy, and is way backlogged... i talked to Freds wife last week and set up an appointment to do a T&T ..and it is at least a month out....so if your not in a hurry......also, look for my post for gunsmiths(under savage 110 i think), there are a couple of names there that can do that, rsbhunter
