Default Best powder for 3" barrel S&W 686 .357

Normally I would go with Hodgdon H110 BUT this may be a too slow burning powder. I suspect I need a bit faster burning powder. With 3" barrel .357's being quite common I have to assume this is not new to this forum.

I'm looking to push a 158 gr. cast bullet at 38 +P velocities.

Suggestions?
