Also there was a question from a boater/hunter in Alaska as to

12 gauge emergency flares could be fired from a 12 gauge weapon

Good chance you will destroy the shotgun barrel.

A 12Ga flare is a total toy when compared to a 25MM flare when
measured on a performance basis, which when you need it is all that
counts.

Consider carying a GPS locator if you seriously need help.
