I once bought an estate that included over 24,000 primers. I shot some and traded many. I think the oldest were Alcan's from the 60's. They will probably go bang but the price is high for not knowing storage, and true age. If they are a year old ask to see receipts or price stickers. In my mind at most I would offer $15 per K. If I buy new and something fails I can expect the manufacture to stand behind their product as well as the store. You are paying pawn shop prices for a no warranty unknown age situation.
