HP In NJ
There is an HP law in NJ, but it's intent is as a sentencing law, to be used in conjunction with other charges, like, say, armed robbery.
You can buy HP in Jersey, you can have (and use, if need be) in your house for your defense, you may have it to and from the range/your place of residence, and you may have them when hunting, and it's appropriate to do so.
This is the first I've heard of the HP ban being a "stand alone" prosecution.
Another note: the "search" that discovered the HP is dubious.

EVEN IF you are one of the 732 blessed carry permit holders in this state, you may NOT carry HP ammo.
I once heard EFMJ whiningly described as developed for "the retired police officers, who can't carry HP"
My response was, "that's all well and good for the retired cops, but what about the non retired civilians?"

Another note: NJ law doesn't have a distinction between felony and misdemeanor. It only has "crimes of the 1-4 degree", 1 being the worst, and "disorderly persons" offenses, such as wandering around town in a drunken stupor.
