>> Manufacturers of ammunition must obtain a license under the GCA for each site at which manufacture will occur; Manufacturers must obtain a license under the federal explosives laws for each manufacturing site and comply with the storage, record keeping and transfer requirements of the law; Manufacturers must register with the Department of State, Directorate of Defense Trade Controls; Manufacturers must pay excise tax on their sales or use of ammunition; Manufacturers of ammunition who import smokeless powder, primers or other components of ammunition must register with ATF as an importer and comply with the permanent import provisions of the AECA; importation of ammunition (including components) is also subject to the requirements of the GCA; Manufacturers of ammunition who manufacture or acquire threshold quantities of COI must complete a risk assessment with the Department of Homeland Security and may be subject to further requirements depending on their level of risk. State law requirements should also be considered by anyone intending on manufacturing ammunition, as licensing and storage requirements may apply. Questions about federal and state requirements should be addressed with qualified counsel. Seems like there is a lot of opportune grey area for the feds to exploit and make the process as difficult as they like. Thanks for the link
