Greetings,
You will have noticed that most of the Hodgdon data for the older projectiles has pressure expressed in CUP so it could be 30 plus years old. The IMR data has pressure expressed in PSI so it is much more recent und used a different method of measurement using electronic systems rather than mechanical. To be honest I would be surprised if they were the same. There are three versions of 4895 marketed by Hodgdons. The original milsurp stuff just called 4895. When this ran out H4895 was manufactured by Nobels and now ADI. Dupont started offering IMR4895 after the milsurp stuff ran out. I have used all but the Nobels manufactured stuff, alas in the days before I had a chronograph.
