No, I don't have a chrono so I have never collected that data.Did you by any chance chorography that load? I'd be interested in seeing the velocity with Bullseye powder. Bullseye is a very fast burning powder and it doesn't take deviation from any set load to really increase chamber pressures. I usually use Bullseye for 38 plinking rounds since you can load a ton of ammo using Bullseye, for little powder cost...
For handguns I have been experimenting with different powders for 50 years. My criteria are recoil and accuracy. Not too scientific I guess.
I have settled on Bullseye for everything up to .38 spl, and Unique for .357 and up. I use 4227 for a few odd things, like real short barrels.
I realize that there are many new powders that may be better, but since I'm satisfied with what I use, I see no need to change.
