Hornady has IMR 4895 data for 129gr cup & core bullets, but it seems to be the most sensitive to case volume/pressure ratio of all the powders they tested.
Max is 26.1gr under a Hornady 129gr lead core, copper jacket bullet set at 2.245", with the slowest velocities of all 11 powders they tested in the 129gr weight class.
