DEar 280 IMP.
Pretty easy job!. If the present 257 Roberts barrel is still good I wouldn`t chop it up but if the rifling is bad or it wont shoot all you gotta do is remove the barrel and send it to a reborer and have the bore redone to 284. The chambering is just a matter of doing the neck as the case is about the same. This is how I do the 338/06s from the 30-06.
