Who knows
Aside from straight walled cases for a minute. Since the area you are going to hunt has apparently allowed only shotguns for some unknown years, I would think there is a reason. Limited hunted space etc. I might skip high wall and find a Browning A bolt in 12 ga. If you still want a straight wall rifle cartage I would chose a 45-70.
I use a 405 win model 95 only because I have one.
