Welcome to the forum.
First thing you need to do is check the regs to see if you will be hunting in a shotgun zone. That will have a lot to do with what gun you select
.
Next you need to check PA for the regs there and the cost and availability of non-resident permits.
Then I suggest you get out in the woods where youi're going to hunt and do some scouting. Lots of scouting.
Hey, once again, welcome and good luck.
