I think that one buy big bore rifles because they are needed for something special and not because they have a bigger caliber and do more recoil that the rifle of the neighbor.

Of course, this assumes that you can handle such weapons. As already written, nowadays it no longer has to be a weapon caliber 50 or bigger. The production of the cartridge 416 Rigby at the beginning of the 20° Century has resulted in some DR caliber 577 Nitro Express remaining in the gun safe. The stopping effect of the cartridge 416 Rigby can be discussed, but a rifle caliber 458 with a strong built-up FMJ bullet is certainly a rifle to use nowadays for stopping and killing the biggest game. Such weapons are also much easier to handle than rifles caliber 50 and above.
