I shoot Winchester factory 38 "Winclean" ammo because it is so clean. In fact, I usually dont bother cleaning the gun when I get home if that was the only ammo fired that session. Now, Winchester is offering the Winlcean powder no. 244 for reloaders. I am curious to know just how clean it is when used with regular primers. The factory loads use a special uber clean primer in addition to the clean powder, but the primers aren't available to reloaders.
