Shooting the 475 Linebaugh requires a great deal of skill/ability. It would be a real asset if hunting very large game or for protection from large predators pushing a 410 HC at close to 1,400 fps. You could also back down to a more manageable 480 Ruger shooting same bullet at close to 1,200 fps for same use. Still very potent.

44 Rem Mag is a pussycat compared to the 475. Much more dedicated to everyday use with a much wider range of bullet weights for a wider range of purposes. It can produce big punch on game with 300 gr-340 gr HC. It can also be loaded down with 180 gr - 280 gr with JHP and HC.

Pretty much depends on your intended use. The 475 Linebaugh is so specialized loaded to higher pressures compared to the 480 Ruger, which is kinda like a 416 Rigby philosophy, lower pressures and lower recoil with big punch. I see the 475 Linebaugh being more of a conversation piece, it’s not a lot of fun to shoot.

BTW as someone else stated the rubber grip was used on the BFR for standard non Bisley. You can obviously tell the difference between a standard vs a Bisley grip BFR or any Bisley grip revolver in one quick glance of the firearm.

If thinking of retaining value and wanting that, skip both and buy a Freedom Arms. There are quite a few used ones out there in 454 Casull in the $1,700 plus or minus range. Folks who bought em shot em once or twice and found out what recoil was all about. Great for killing anything massive, but how often do you really do that with a revolver.
