I have used it for years on many pistol calibers (.38. .41, .44, .45) and it is a very useful powder. It's really not dirty unless you load it too light and the case doesn't quite swell enough to seal the breech. A lot of powder measures don't like it and will chop grains. It can also bridge in the meter so give it a little tap every time you dump a charge to ensure you get it all. Crunchy but good.
Hey gents...thanks for the replys. I have found a couple pounds of HP-38 and decided to go that route. I was looking at a burn chart and it showed Red Dot burns faster than Titegroup. My guess is it would be as bad, probably more smoke than i get now. Thanks again guys.
