North Georgia Black Bear?

Planning a 4-person Black Bear hunt in North Georgia. Party will my younger sister, her fiancé, my wife, and myself. We’re thinking about renting a cabin or camper near Chattahoochee Nat’l Forest.

I’d most likely use my .270 or 12ga (I prefer TTSX projectiles in both)

I believe my sister & her fiancé will be using either 45-70 or 12ga if I recall correctly

Any advice or inputs would be very much appreciated. We’ve never hunted black bear, but it’s something we wanted to do as a shared trip to celebrate both of our birthdays.
