The Philadelphia area is large. When I lived near the Art Museum I shot at West Chester gun club, Delaware County Sportsman and Delaware County Field and Stream. None is more than an hour from Center City. There is also Pine Valley adn Pine Belt in New Jersey that would be less than an hour from Center City and a lot less if you live on the New Jersey side of the Philadelphia area.
If you live in the northernm part of Philadelphia there is Bucks County Fish and Game. I am not very famialiar with the Southern part, but there should be lots there too.
The hard part would be deciding where you want to go. Lots of choices.
