Personally and this is just me, I would use #11 mag caps or better yet the RWS Dynamit Noble 1075+ caps. Normally you can get a better cap seal on a #11 nipple.
Have you thought about using Triple Seven 2f powder - you can find it in many places than true Black Powder these. It is a very energetic powder and produces the about the same if not higher ballistics as does Swiss. Also is way less corrosive than real black powder.
