Great start, thanks! I just so happen to have 1k PMC once-fired saved up for just such an occasion. I also have 500 Federal SPP, that should interchange with the Winchesters just fine? I was worried that I would have to use magnum primers for this. Most of my shooting is during warm to hot weather. Is the AC temperature sensative? I will have to research which of these powders meter well from the Lee Auto Disk as that is all I have. Also, I need to check the Storm Lake barrel to make sure it will take a round loaded that long. Guess I should buy some bullets (wish I could find a smaller quantity to test with).
