^^^I agree. It seems the infatuation with the really big bores like the .460 and .500 mags has dropped off a bit from those that just want to impress their friends at the range. The demand has changed to those that are looking for a good deer hunting revolver platform. Many folks have come to realize also that the only way most folks can afford to feed them regularly and/or find the ammo they need, is to reload. This is similar to the infatuation on Model 29s, because of the Dirty Harry movies. same thing. Many folks didn't realize how much recoil and noise were produced, nor did they expect ammo to be as expensive as it was, even back then. For those without a real need or desire, the new wore off quickly.
Again, whether the X-Frame or the BFR, the .460 is not for everyone. While the bigger X-Frames can make it more pleasant to shoot at the range, the concussion and muzzle blast will still make your ears bleed if you do not wear appropriate protection. Factory ammo, even the cheapest is over a buck and a half a pop and most legitimate hunting ammo is about 2-3 times that. Even reloading it is expensive. While there are a lot of haters out there, IMHO, there are few handgun calibers that are more perfect than a .460 for a primary weapon for hunting deer. That, even tho I still hunt deer with .357s and .44 too. The accuracy they produce out to 100 yards and beyond and the terminal performance with appropriate bullets is just amazing for a straight-walled handgun caliber.
