I wonder if they have a limit...

Pistols put holes in people. Rifles put holes through people. Shotguns, at the right range with the right load, will physically remove a chunk of shit off of your opponent and throw that shit on the floor.

Well, I guess the whole point is to make sure they don't miss...

I was just quoting Clint Smith, but yeah, it's a bit difficult to miss with a shotgun.
