IMO, Schuetzen is a much faster and cleaner powder than Goex. Yes, as Swiss is fast, it is too expensive for non target shooter and many target shooters alike to buy.
What are you using for priming powder? Are you new to Flintlocks?
Hopefully I can help you as I have recently started the "rock-lock" game, but I have learned a lot from many of the best flint shooters at Friendship.
