Building on Mike's reply a bit...........To the best of my knowledge, Sharpsburg Arsenal no longer has a shop open to the public. Ian lives in Shepherdstown, WVA, and is probably one of your best bets if you can schedule a visit with him. And if you are at Frederick, you will be less than an hour from Gettysburg - several options there, and at least two that have bullets/cartridges/butllet related items from the Dean Thomas collection for sale. And if you see a bullet or two posted on the Thomas Publications web site you are interested in, might be able to contact Jim or Dean to see it in person. And lastly, there are numerous antique shops in Frederick/Hagerstown/Harper's Ferry that have CW bullets for sale. I'll picke up a couple of pretty scarce ones at those shops over the years
