Was at the Heritage Guild in Branchburg today, and a guy was buying ammo. They logged it in the book and then wanted him to sign the book. They told him it was NJ law and that the State Police liked it done that way. Has anyone heard of this before.

I've had my purchase logged at efingers, didn't have to sign anything. I've long since stopped buying ammo locally though.

 

Edit: I've bought at ranges with no log book.

if you're going to shoot the ammo on site, like at the range , it doesn't need to be logged .
