Daryl, speaking of Alliant 20/28 powder, an 8 pound jug just sold on Gunbroker for $595. + $50. shipping + Buyer's state sales tax + 1% GB "compliance fee". Brisk bidding with 25 bidders. Let's say the Buyer lives here in PA where the state sales tax is 6%. That would make the total price: $690. for 8 pounds.
