I've never seen handgun data for titewad.
I've used it for 12 gauge shotshells. they aren't joking... a little goes a long way.
I think this propellant burns much too fast to be used in anything other than larger gauge shotguns.
If i remember correctly, this powder is always leader on the burn rate charts.
If you want a good dual purpose powder, I favor hodgdon's Clays
