If you are interested in another caliber altogether, I think it may be best to decide what you like and want,talk to the gun dealer of your choice, and trade your current rifle. Probably gonna cost a good bit less in the long run. Perhaps some of the others around here who do this for a livelyhood can give you a ballpark cost for a rebarrel job. I just had a 7 Mag done with a Shilen tube, and it's not that cheap. New bedding involved, also. JMHO----
