Blue Dot
No, I didn't put 'em through the chrono, but I know I've loaded .38 loads with Blue Dot that ran under 400 fps. A few years ago I had a pile of .356 cast 100gr for .380, and I decided I'd make a few .38 Special gallery loads, and I chose Blue Dot. I could see the bullet in flight shooting at 50 yards.
I calculated the velocity using QuickLoad, and the result was sub 400fps.
As mentioned, Blue Dot wants 'more power.' It's not for plinking loads. I like Blue Dot, but in my .38 loads I load to the top end of 'safety' as published, use brass that's +P, and use magnum primers. It's just NOT suitable for plinking loads like, say, Red Dot or Bullseye are.
