I looked at the PAUFA, and did not see any guidance on use.
If one owns an acre, can one shoot a .22 in one's own land? There would be other lots and homes near on similar sized lots.
There are no state restrictions on shooting on your own property so you would not find anything in the Pa UFA. You would have to check local ordinances for that..
Make sure your bullets do not leave your property line and you should be good. My local township also has no restrictions against shooting on your own property, but I don't do it because I have neighbors in just about all directions. And the range is only about 15 minutes away.
No open carry in Philly.
Your comment is so brief I'm not sure what you meant. Open carry is legal in Philly with a license/permit...
