I have much the same 1,500 pounds or so of #8's, 24 pounds of Clay's powder, and a couple cases of wads. The shot I bought a ton of, (80 bags), back in the mid 90's direct from Scott Shot up in St. George Utah, for just $12.50 @ bag.
My wife told me I was crazy for buying so much. Now she thanks me. I am down to my last 4,000 primers however.
I finally got around to dusting off a shot maker I bought at a swap meet years ago. Had to fix the switch but it worked great and was not as much trouble as I thought it might be. Cranked out 30 lbs. of #8 in short order. Previously I had been using reclaimed shot but I finally ran out so I decided to make my own.
