I wouldnt buy the BFR unless it is one of the newer models with the Bisley handle. Plenty of shooters are dumping 475's and 500's with the plow handles to replace them with Bisleys.
If the BFR is a Bisley I would jump on it. You can load it down and it would be a super deer slayer. The quality and strength of a BFR is well above a Ruger.

My biggest fear is when I die my wife will sell my guns for what I told her they cost.
