x2 to what rifleman said.
Yes, the Blackhorn is dear, but the cleanout in the field is much much easier than either the pyrodex or the triple seven that I've run previously.
When you have lots of running water around for the cleanup it doesn't make a big difference, but I was having trouble even swabbing the bore between shots with the other two, and it seems like I could nearly load all day without a major cleanup using the Blackhorn 209.
Hope that helps. If you're in the Peterborough area and want to give it a whirl send me a pm.
Cheers,
