(Selling would have to be at replacement retail value plus shipping/tax/haz to get the powders I need. )

I have:
5lb jug of Alliant Reloder 17
8lb jug of IMR 4831
8lb jug of Alliant Reloder 33

I'm looking for: (unopened, recent vintage)

I travel between Newark DE and Bedford PA once or twice a month and can usually arrange meetings along that corridor.
