Dirty cases indicate insufficient ignition. You need either a hotter primer and/or heavier crimp.
Personally, I did not get satisfactory results in my 45 Colt rifle with H110, including issues like this. Accurate #9 ignites easier and burns cleaner, and gives me all the velocity I need. Just my perspective.
