Six, You didn't say what kind of semi auto you purchased. There are some semi-autos that can be motified to be legal in Pa. If you happen to have a AR-15 type rifle, you can take out the gas tube and plug the gas port making it a legal "manually operated" rife in the State of Pa. I have used the same Colt AR-15 model 6721 for the last five years. Be advised, if you hunt a popular area, every hunter will ask you " what king of gun is that" and if you get checked, the Game Warden could send your semi auto type rifle to the State Police crime lab to have it checked out. I use my AR-15 a few times during the Deer season and only on private land. I hope this helps. Doc in Pa.
I have never been able to understand why the use of a semi is Illegal in Pa. I own a few of them and hunt West Virginia also where they are legal. Take anyone that knows how to shoot a 760 gamemaster and they can shoot as fast and as many rounds as a semi, Heck I have seen guys in my lifetime that can shoot a bolt quite fast also. No matter how you look at it there's still lead flying around ...
Semi's offer a nice advantage though you can normaly get a smooth follow up shot if needed. I can't remember when the last time I needed a follow up shot. I think it's a game commission thing. I asked a game commission officer one time years ago why the use of a Semi was Illegal and the smart assed answer he gave me is because its the law, just as I figured I would receive doubt if he new either.
Its not the people that know how to shoot a semi-auto that worries me. Its those who don't take the time to become proficient, and who would use a semi as a way to get around their lack of ability as a shooter. The spray and pray crowd if you will, would definitely be a danger in the woods. For that reason I'd rather not see semi-autos made legal to hunt with.
