Don,

The dog powders (blue, red, and green) are shotgun powders that can be used for handgun cartridges. Bullseye is a fine flame powder that gives fantastic results, but can easily be double charged. Winchester W231 burns close to Bullseye but is a ball powder. If you have an insufficient crimp,both Bullseye and WW231 will leave a black film residue. I have used WW296 in 357 with success.

I can't really speak to any other pistol powders, since I haven't used them. For rifle loads, I have used: Varget, IMR 4895, IMR 4064, IMR 7828, and IMR4198.

If you don't pay attention while throwing charges with Bullseye or WW231, and if you throw double or triple charges, you can risk injury by blowing up a handgun. This emphasizes that you can't be distracted while reloading.
