Yes! Absolutely!!
Specialized? Absolutely!!

Stalk and walk with that double for sudden trouble and use a scoped bolt gun for the set up money shots on game.

But if it does hit the fan and your life is at the mercy of teeth, claws and fangs in some remote farflung wilderness what would you rather be doing?
Trying to rack that bolt in a sweat or shooting that 2nd barrel into the terror attacking you.

How much is your life worth??
I think you need both type guns and a good PH backing you up as well.
