Midway seems to be the easiest place to find primers, but you can only buy ONE brick at a time. Unless you can find some powder or other primers to go with it, you take it in the hind quarters with hazmat. Brownells seems to be next easiest, and the limit is 2 bricks... but it is adult signature REQUIRED... which really bites for thos n.v of us who have jobs. However they will deliver to an alternative address. Most suppliers do not require signatures, but for some reason, Brownells does. I don't order from them anymore. Good Luck.
