Jim (the father, I believe) is also a black-powder enthusiast. He may be a knowledgeable resource.
Yes he has black powder percussion caps, number 11's. He also has some black powder tools and accessories. He recently repaired my .45 cal. Musket.
I find it unlikely that they will answer this due to their limited online presence. However from what i have seen they have a lot of equipment and materials for black powder firearms and reloading cartridge firearms. So i find it unlikely they will not have those. I will be in there tomorrow(Monday) and i can check for you if you would like.
