Living in the peoples republik of Maryland makes buying black powder difficult and the laws are very restrictive on the amount you can store - they even count the weight of unmentionable primers against what you can store. I've been thinking of diving into the world of matchlocks and wonder if pyrodex or other BP substitutes will work? I've been a flint and percussion shooter for over 45 years and now rarely use my flintlocks as I've nearly used all my holy black. Thanks for your help.
