Big thats what most guys think anyway (overcompensating!). But I have one for two reasons. I wanted a gun that easily took deer at 500yds plus without concern for lack of power or rainbow trajectories. To get a bullet to 4,5,600yds and still pack a wallop its simple laws of physics, they gotta start out FAAAAST!
Oh and the other reason why... because I wanted one!!!

ps
BTW Big, with any one of the guns you mentioned, you wont have a need in the world for either of the other two! But then again, when has " need" ever replaced a desire for a full gunsafe???
