Under the insane gun laws here in Massachusetts, brass and other components are regulated as "ammunition" and the AG claims that you need a Massachusetts ammo dealers license to sell such obviously dangerous items as spent brass to Massachusetts subjec . . , er, residents. That is of course unconstitutional, as the point of sale for mail orders is considered to be where the merchandise is given to the carrier, and therefore the state where the material is received does not have jurisdiction. Regardless, some dealers - including all of the really large mail order houses - have caved under threat of lawsuit, some others - generally smaller, so thinking they'll hide in the weeds - have not, and individuals for the most part fly under the radar.
