These days, I'm partial to Triple 7... The crud ring is annoying, but if you just wipe with a moist (doesn't have to be wet, just moist) patch between firings, it is really not that big of a deal.
110gr 777 under a Sierra 240gr JHP in a Hornady sabot groups at about 1 1/2 inches at 100 out of my CVA Optima... and chrono's at about 1880 fps.
Cleanup is a snap, and no stink. The wife likes that.
Works for me.
