From what I have read of the law I can find nothing relating to reloading components. There may be a definition buried in the Penal Code that defines ammunition though that may include components. I have been looking but as of yet have been unable to find anything. Online merchants will not ship anything to NY if it's illegal here as they would be criminally responsible if they did. I ran into this with high cap magazines that I am allowed to possess due to my peace officer status, no one will ship them here though so I have to go through a local dealer and pay their price which is generally a lot higher. Good luck finding powder or primers though, everyone is out of stock.
