Challenger 12 Gauge Blue Target Shotgun Hulls

I have a bag of 400 Challenger Blue target and slug hulls ready for reloading.  These are all 2 ¾ inch low brass/nickel 12 gauge hulls.  I do not believe this quantity will fit into a flat rate shipper, so buyer will either have to pick-up or expect higher shipping costs.   Selling for $30.  You can pick-up at my location, or I can ship to you at your cost.
