RE: .480 ruger or .475 linebaugh ??
Hi whelen36,
I could very well be mistaken, but I believe the .480 Ruger can be fired through a .475 Linebaugh just like a .38 Special can be fired through a .357 Magnum or a .44 Special can be fired through a .44 Magnum. The differences being the OAL of the cartridge and the inherent operating pressure and energy. If that is the case it would seem to make the .475 Linebaugh more versatile. (Assuming you have a choice of chamberings....not all guns offer that.)
Good luck.
Dave
