You wrote it. " you cannot use firearm magizines or clips for packing ammunition unless they completely enclose the ammunition" . If you can see the cartridge its not fully enclosed. If the Magizine has a cover you good. Sneeky pete, ammo armor and Glock make these covers. There are a few airlines that have regulations reguarding ammunition and firearrms that differs from TSA policy. But it is not TSAs responsibly to enforce these policys.
