Re: Semi- use in Pa.
Not sure what the reasoning is behind it. I don't see the problem with semi autos for deer, just make a magazine cap at 4 or 5 rounds. That would stop guys with various military arms from blazing away like an idiot for 30 rounds. Something like "Center-Fire auto loading rifles designed in a manner that no more than 1 round be fired for each complete trigger depression, with no more than 5 rounds total in the weapon between chamber and magazine".
If the people in the know were really worried about assault rifles they could put a caliber restriction on it as well. 30 cal or higher, something like that.
