I'm shooting .38 specials and .357 and using Unique powder. For target loads I'm down around 3-4 grains with 148g SWC and after a few hours at the range my nice shiny SS Taurus Tracker looks ike it's been recovered from a house fire! Can anyone recommend a cleaner burning powder than Unique? The 38 and 357 are mostly target loads but I have upped the charge to 9.6g for 125 JHP when I want some oomph in the 357, which suprisingly does seem to burn cleaner at the higher loads.
