A hearty welcome to you, Bill. There are a few of us who are interested in the percussion Schuetzen rifles. Very few of us unfortunately. 

I have a meager collection, several of which are .40 caliber. I shoot round balls and picket bullets and short hollow based bullets. Have found that the round ball out to one hundred yards works as good as anything else.

Bill - log onto the Muzzle Loaders Assoc of Great Britain forum.  Look around there for loading info and bullets used.  They shoot matches out to 1200 meters with ML and the gents are very good at it so you should find excellent information...

Swiss makes excellent powder and so does KIK and the new Goex's Olde Eynsford.  Swiss and KIK use Alder Buckthorn for their charcoal which is the best wood for black powder. What your looking for in BP is moist fouling and velocity.  Hint - Alder Buckthron charcoal, the 'Engine of BP' generates much higher velocities for original gunpowder.  I've shot cases of Swiss but my favorites now are the March 2009 lot of KIK and the new Olde Eynsford

No, this loading data is not solely for Goex powder.  It was developed by Curtis's & Harvey's in Ardeer, Scotland - recognized to be the best black powder made.  Unfortunately, C&H is no longer in business
Good Luck and Shoot Straight
