I'm looking at some data in a Handloader article (June 2006, #241). Brian Pearce is loading .44 Magnum with 200gr. XTP-HPs with 11.0gr. Unique for 1145fps in a 6 1/2" pre-29. That should be close to your target for a 4" barrel. He refers to it as a "Midrange .44 Magnum load".
12.0gr Power Pistol will do ~ the same thing.
