I received my MG order within two weeks of placing it, whereas I'm STILL waiting on .357 158gr JHPs from Zero/Roze. I'm not sure about the number of lines working at the same time, but in talking with someone from Roze it sounded like they put all their production against a single or few bullets for a while, then retool, etc. If you place your order after they've "moved on" and they're already out of stock, well, you wait a while I guess.
