one advantage would be the platform of the gun, for instance the tc encore. I have a stainless encore prohunter with blackpowder barrel, 7mm-08 barrel, 22lr barrel and 20g barrel. Put it all together in a rifle carrier and i could hunt pretty much anything in north america except maybe a griz. Another thing i like about that setup is i always have the same trigger, so once i get it like i like it its done and its familiar.
