Greetings,
Best to treat them as different powders and use the IMR data for IMR 4895. The IMR data is more up to date as the H4895 data is till in CUP rather than PSI. The change to PSI occurred some years ago and revealed some problems with some of the CUP data. My old Speer manual lists 43.5 grains of IMR4895 as max. Makes you wonder about the Hodgdons/ ADI data a bit.
