Just a question about having a 5 shot cylinder made, and converting the revolver from a 6 shot. The strength of a BFR frame, and the thickness of the cylinder is really beefy as it comes with 6 holes. I have many 5 shot guns, but there all over 41 caliber, due to ( like cartridges with a .454 or 475L parent case) the extreme pressure of a wildcat cartridge. Even on my .356GNR revolvers, a 41mag parent case necked down to .357 there built on 6 shot cylinders. I don’t think you could overload a heavy hunting bullet in a 357, that wouldn’t be fine in a 6 shot cylinder.
