Might want to answer the question "What am I going to use it for"? The .475 is quite a step up from the .44 Mag. If you are going to load it down to .44 Mag levels, why put up with the extra size/weight of the BFR and extra cost of ammo/components? If you just want a Big Bore (been there done that with both .475 LB and .500 JRH) then get the BFR.
FWIW,
Paul
