I have a range in my back yard.So after firing the pistol 4 times I bought it in and cleaned it.When I ran the patch down the barrel ,,I couldn't feel a crude ring.So I am a happy camper..I hunt with different rifles and for the most part,I hunt with white rifles.I have never had much of a crud ring with them,shooting musket caps.I am going to break down one day and buy some Blackhorn 209 and try it.I stared at it the other day at the local gun shop,,I was thinking to myself,that sure is a small bottle,,but I also noticed there was a lot of dust on the triple 7 and pyrodex.
