Federal law does nor prohibit possesion or use of Black Talon ammo. However, be aware of any state or local laws that may make them illegal. I have a full unopened case of them. They are the same as the Winchester T series now minus the black coating. The black coating was Lubalox which simply prevented the copper bullet from fouling the riflings in the barrel.
You cannot legislate the poor into freedom by legislating the rich out of freedom. What one person receives without working for, another person must work for without receiving. The government cannot give to anybody anything that the government does not first take from somebody else.
