Things have changed so much over time. I just saw the post where only one place in Arizona has black powder. I bought my first replica black powder firearm, a Navy Arms Pietta Remington, in December 1980 while stationed at Fort Huachuca. It was at a store called the Emporium across the street from the OK Corral. The guy who sold it to me told me I could get the powder at a certain store in Sierra Vista. That store was only a few blocks from the main gate of Fort Huachuca, and I bought several pounds of GOEX from them. I believe it was some sort of hardware store, because I bought a cast iron pot to melt lead also. If I remember correctly it was $7.50 per pound. When I bought the revolver I got a case and a number of tins of caps also. I have also been reading the posts on percussion caps and the costs when one can find them. Except for musket and occasionally tinkering with the revolver I have shot flintlock rifle exclusively for over 20 years now. I believe the last CCI caps I had bought was $4.00 per 100. In the revolver case I still have one of those original tins of caps unused I bought in 1980. It has the red Navy Arms sticker on top and on the bottom is priced at $2.50.
