Before you jump the gun, i spoke with out state representative at our local sportsman's club meeting a couple weeks ago. Even though the law passed making semi autos legal for hunting in Pa, they have left it in the hands of our backward thinking Game Commission to set the regulations. As of now, no decision has been made regarding calibers, magazine capacities, and species that will be allowed. He has heard rumblings that any caliber will be allowed for predators such as coyotes and groundhogs, but will be limited to 5 shot magazines. As far as big game such as deer and bear, he feels they will have a minimum caliber (larger than 5.56/223 ) and also be limited to a 5 round clip. Remember, this is the state that has a "muzzleoader season" but still limits you to using a flintlock.
