There's a case where the shooter has too much gun. Very few people can competently shoot a .454 beyond 7 yards. Recoil is severe no matter who you are. And while the Taurus Raging Bull is without a doubt the most accurate production revolver I've ever shot, the grip frame is somewhat less than optimal for a hoss like the .454.

I've shot the Raging Bull in .454 and .480, and I'll take the .480 EVERY TIME; much more fun to shoot and with an LBT LFN bullet, I think it just out-performs the .454 for less recoil.
