Caps here are as high as 8$ per tin for #10/11, and 10$ for musket.
A few weeks back, fffg type powders suddenly petered out as well as balls and caps. Me and a buddy drove 3 counties one day, found a grand total of 400 balls, 4# powder and about 5 tins of caps.
Only fffg left on the shelf is app, and i won't use it. I gave away a just opened pound to another shooter in our group. It is granulated more like ffg when compared to goex or pyrodex.
