PA is one of the few states that disallow the use of semi-autos for big game. I have no idea why. It seems that the PGC continually suffers from rectal/cranial inversion when it comes to major changes in the game laws. Another thing that bugs me is not allowing the use of air rifles for small game. The air rifle technology has come a long way since the ban was introduced way back when. They can set a KE minimum (velocity and pellet diameter) like they do with archery gear (draw weight minimum).
Then there is the no Sunday hunting which is also ridiculous. No reason in the world why Sunday hunting shouldn't be allowed.
