Unsure if this is the correct place for this, but does anyone in the Southern LA/MS/AL have tips for locally sourced 1LB packages of Alliant RL-19 powder?

Or would anyone be willing to trade or sell 1/2 pound? I have RL-15, Blue Dot, Universal, H335, WSF, and HS6 powders available for trade. Looking for 1/2 pound. I am willing to travel.
