As a new jersey resident, I purchased 9mm and .45 acp rounds of the federal EFMJ. I bought them before guard dog came out and I keep my g17 and xd45 loaded with them. The law has alot of grey areas regarding the possession and use of hollow nosed ammunition. This is from the NJ state legislature website
f.Dum-dum or body armor penetrating bullets. (1) Any person, other than a law enforcement officer or persons engaged in activities pursuant to subsection f. of N.J.S.2C:39-6, who knowingly has in his possession any hollow nose or dum-dum bullet, or (2) any person, other than a collector of firearms or ammunition as curios or relics as defined in Title 18, United States Code, section 921 (a) (13) and has in his possession a valid Collector of Curios and Relics License issued by the Bureau of Alcohol, Tobacco and Firearms, who knowingly has in his possession any body armor breaching or penetrating ammunition, which means: (a) ammunition primarily designed for use in a handgun, and (b) which is comprised of a bullet whose core or jacket, if the jacket is thicker than.025 of an inch, is made of tungsten carbide, or hard bronze, or other material which is harder than a rating of 72 or greater on the Rockwell B. Hardness Scale, and (c) is therefore capable of breaching or penetrating body armor, is guilty of a crime of the fourth degree. For purposes of this section, a collector may possess not more than three examples of each distinctive variation of the ammunition described above. A distinctive variation includes a different head stamp, composition, design, or color.
(2) a. Nothing in subsection f. (1) shall be construed to prevent a person from keeping such ammunition at his dwelling, premises or other land owned or possessed by him, or from carrying such ammunition from the place of purchase to said dwelling or land, nor shall subsection f. (1) be construed to prevent any licensed retail or wholesale firearms dealer from possessing such ammunition at its licensed premises, provided that the seller of any such ammunition shall maintain a record of the name, age and place of residence of any purchaser who is not a licensed dealer, together with the date of sale and quantity of ammunition sold.
There are two other paragraphs that talk about exemptions for military, law enforcement members and nuclear power plant employees
In section 2C:39-6 there are things that cover exemptions for the use of firearms but it does not specifically go over hollowpoints
The funny thing is that when you read the main part, it seems as if the law was enacted because whoever made it thought that hollow points were better at penetrating body armor. Idiots
