I only have limited information, but Around St Augustine, Florida. There is a gunshop with lots of powder and some primers and most important of all: Reasonable Prices.
My friend Bob was down there last week and found this place. He twisted and broke his ankle trying to take a picture of the store's sign. Didn't get the picture, can't remember the name, and had surgery last Friday to repair his ankle (so in his drug induced state, I can't grill him too hard!)
I think the local members have been holding out on us for fear we would buy everything. I am sure we would!
