Since I promised I'd vote on some of these. I don't know much about Supernatural, so correct me if I'm wrong about anything:

Mundane Weaponry: Dean Winchester wins. Semi-auto, more rounds. On top of that, it's a common gun that he actually knows how to use; Kayneth has an improbably rare gun, and combine that with his distaste for non-magecraft combat anyway and you've got a weapon he doesn't know how to use.

Supernatural Weaponry: Dean Winchester wins. Volumen Hydrangeum has some very notable weaknesses, which can be assessed in a matter of minutes. Its main form of attack, its tentacles, are only really powerful at the tip, as they're used in a whipping motion. Further, they move slowly enough that Kerry doesn't even need Time Alter to dodge them once he realizes this. Further, Kayneth will need to concentrate on defense to the same point as the Thompson Contender, as it has comparable muzzle velocity and a larger cartridge load (don't ask me why the Calico, with a higher muzzle velocity and similar caliber, was able to be blocked; magic works in dramatic ways, I guess). This leaves him vulnerable to a surprise attack.

Overall: Overall, I think Dean Winchester should be able to win, though not without difficulty. This comes down to Kayneth's personality; he is far too arrogant, and is very easy to trick and trap because of it. He tends to grandstand and show off, both of which are deadly in a fight against someone who has access to similar power. Basically, he has the tools to be effective, but not the personality to use them to the fullest. Dean has both.
