I am not sure I would try to use a .22 mag on a black bear... In all likelihood, you would do nothing more than piss it off. Even two legged folks, .22 mag doesn't have much knock down power. If it is coming out of a rifle barrel and you are using a semi auto where you can place multiple shots on target, them maybe...

18 Pa.C.S. § 6106: Firearms not to be carried without a license

(a) Offense defined.--Any person who carries a firearm in any vehicle or any person who carries a firearm concealed on or about his person, except in his place of abode or fixed place of business, without a valid and lawfully issued license under this chapter commits a felony of the third degree.

So in other words, even though it's your land, you cannot conceal carry without a LTCF. They are not hard to get in PA, so why not get one and then you can carry most places you like...

Now open carry is a completely different beast. Have at it! PA allows you to open carry in most places. You may get stares and the cops called on you because people are ignorant of the law, but it is completely legal to open carry most firearms in most places in PA. Just stay out of Philly while doing it and you're fine... It is illegal to do so there unless you have a LTCF. Then you can open carry, however many Philly cops have a negative opinion of open carry and will treat you like trash when they come in contact with you.
