So far, I've only shot pyro pellets with my Encore. Doesn't seem to burn too clean. My first wet patch comes out completely black. It takes 3 or 4 to get anywhere near cleared up. On the range I run a couple wet patches followed by a couple dry ones. Also shot a 209 cap to clear out any cleaner in the breech plug.

I'm going to try the 777 pellets my next time at the range to see if they burn cleaner. I'm also interested in trying some powder.
