I talked to Taurus on the phone the other day about the RB 500. Its being held up pending SAAMI testing to standardize the 500 Mag load. They said probably 4th QTR of this year or 1st of 2005 before they will be out. So far nobody has proved the me that the Raging Bulls have the QC problems that some other Taurus products seem to suffer from. Did not get a price from them. My guess, a little less than S&W. The pictures I have seen were a 10" barrel model that weighs 72 oz.
