I haven't tried to find it commercially yet. The wife found 3 1/2 boxes of it at good prices this past weekend at a gun show. All Factory. I seem to remember that both Cabellas and Sportsmans Warehouse both had it from time to time. I don't remember the pricing though. I'll let you know what I find in the stores.
In my case the expense will be the reloading dies. I found 80 new cases at the show as well. We will shoot the factory stuff this morning as I haven't picked up the dies yet.
