Darkside, just a comment about getting to PA. Consider avoiding going through NJ. They are so anti-gun that there have been cases where, despite FOPA, travelers were jammed up on firearms charges just to make life hard on them. They got off, but only after a ton of time and money.
I can't remember where I read the above, but the article suggested printing and carrying
this page from the New Jersey State Police site that describes NJ's requirements for following FOPA and passing through the state. It might keep an ignorant and over-enthusiastic trooper from following through with an arrest.
One more thing. Hollow point ammo is sort of illegal in NJ. "Sportsmen" can only possess and transport it under very narrow conditions
described here on the NJSP site: directly from home to range or field, etc. It doesn't seem clear to me that NJ thinks FOPA protects you from travelling through NJ with hollow point self-defense ammo like 9mm.
I just bumped this thread asking about transporting hollow points through NJ. In the post above mine some poor guy travelling from ME to TX got jammed up on a bunch of charges, one that stuck was "illegal possession of hollow point bullets".
