what's better than a full auto shotgun?
Laughing maniacally while you're firing a Grenade Machine Gun, normal or Mercy, at a pack of half-a-dozen Deathclaws as they meet their demise before they can reach you? And in third person with the Pre-War Spring Outfit and a hat to boot? Just sayin'.
Edit:
Anyways, I actually preferred using the standard Hunting Shotgun compared to the Dinner Bell due to the Long Tube modification for the standard. Though 3 shells difference doesn't seem like a whole lot, there's a lot of times with the Dinner Bell when I was caught in the middle of reloading during a battle. Maybe should I aimed for the torso and not the head...
