I have the percussion cap maker on order, but will not be using it for awhile. Just checked my go-to black powder dealer for stock and this is what he has on hand (and not at jacked up prices):
74,000 RWS 1075+
500 Remington #11
100 CCI #11
That is the quantity available after my order of 1000 ($103 shipped to my door) - www.addictedtoblackpowder.com in Mineral IL
