I started out using Win 231 but when powders started to get scarce, I loaded up on Titegroup (16 lbs because it was in stock locally and I really lucked out price wise). I've been very happy with TG but will probably find an excuse to pick up some 231 at some point. I've also used Power Pistol, Bullseye, Unique, and Win WSF with good results in pistol cartridges.
