BH209 is my current favorite too Dave for my TC Pro Hunter. I like it much more that T7 which I previously used. Cleaner, no crud ring plus outstanding shelf life!!
I also have a White Rifles Custom Super 91 .504 built by "Doc "White himself which I run 3fg Swiss through in shooting heavyweight conicals. It's my back-up in case on a trip my TC fails me which likely will never happen. It's a "slip fit" type custom Wilson Barrel designed to shoot .503/.5035 conicals in 460-495 grains. Swiss is the cleanest real stuff that I have found!

I've never shot Swiss. Probably because I've not seen it on any shelves of the local gun shops that I visit. And around here (Pittsburgh Pa.) when I do go to an occasional gun show, the vendors won't bring BP to 'em because BP is an "explosive" unlike gunpowder, which is a "propellant". So, in this neck of the woods you can't get from here to there without going thru a tunnel. It's a fact of life. And, you can't take ANY explosive (i.e. Black Powder) thru ANY tunnel without an act of congress. So the vendors just don't bring BP with them.
On weekends in the fall a bunch of us will bring our M\L's to the range for a plinking shoot. So, in addition to my flinters I will bring the in-line. For plinking I'll just load up 50gr of Goex FF and ram a RB down it. It's very accurate at 25 and 50 yards and no recoil at all. Dirty as all get out to clean....but fun to shoot.
Pyrodex is a great product as long as you understand it's properties. When it ignites, it leaves behind an oily residue to protect the bore should you be less than fastidious in prompt cleaning. A great feature I'll admit in comparison to black powder leaving a dry and caustic ash. Note: It's probably NOT the best choice for flintlocks! I learned that the hard way. After a few shots down a 50 Hawken's bore the frizzen was slick and wouldn't strike sparks so I could reach over my head and touch off the pan with my cigarette. All was fine until my buddy experienced this and I approached from the side to assist ignition. The unburned granules to the outside of the flash became birdshot into my fist. Ouch! I still carry the tattooed reminder of those grains in my knuckle. A valuable lesson indeed.
