Well, OK, but I bought 200 cases from them recently, and they did not say anything about being a customer for one of their guns or conversions. Just shipped me the cases when they got them in. (Took a LONG time to get them, but they finally did come.)
I checked Midsouth again, too; their site says that they have been ordered and for 'due date', it just says that they are 'overdue'. ? ? ?
P.S. Since primers now cost around $35/1000, the FA price for primed brass is about the same as that for the unprimed from Midsouth.
