In my oppinion and experience, I don't see any major issue with using shot guns, and as far as being safer the rifles, my answer would be, all fire arms are dangerous and need to be used with exteame care regardless of where you are using them, as long as they are permitted to be used.

Prictice good hunting safty and use your god given common sense.

KEEP HUNTING THE GREAT OUTDOORS & GOD ALIVE, PASS IT ON!
