I also prefer the Riot Shotgun.
The Dinner Bell has better damage and spread.
Since it's better than Riot Shotgun I don't see the point in picking the lesser variant.
For me, it's just not worth going through the Bleed Me Dry quest to get Dinner Bell.
That quest set was definitely a one-timer for me. I hate The Thorn and everything about it, so I don't even bother with the place anymore.
Just my preference. :shrug:
The DAM difference is only minimal when you consider the Riot Shotguns high rate of fire, Hunting Shotgun is good for normal use, but if a Deathclaw comes sprinting at you, the Riot Shotgun can put out shells far faster than the Hunting Shotgun, and reloads quicker too. Everyone has personal things they look for in a weapon, might be DAM, DPS, Spread, Clip size or even the type of ammo it uses.
Exactlly.
I tend to work my way up through the shotguns as I level, breaking down shells as I need to for whatever gauge I am using at the moment.
Once I come across the riot shotgun, I sell my Hunting Shotgun (by then, most certainly modified) back to Gun Runners and never look back.
The way I play (maybe it's too much Resident Evil, LOL!) shotguns are CQC panic weapons, anyway.
