I'd like mine in .410
Well, if you want a jet-powered bicycle, it's your God-given right to have one. I guess I start asking "why?" sooner than some, even though I know the answer is "Murica." And that's a fine answer, to be sure.
Having shot the .460 and the .500, and even a .308 handgun, I can tell you that it is a profound experience. I can also say that, for me at least, it wasn't necessarily a pleasant experience - with the exception of the .308 which was a bolt-action silhouette gun. That was fun to shoot. But the revolvers? Not so much.
But that's me. Everyone else should follow their particular bliss.
