Alright was looking through some of my loading data, and I was wondering since Hodgdon now owns IMR or Vice Versa, is IMR 4350 and H4350 about the same? Could I use IMR in place of Hodgdon.
Thanks Guys

Ok, so if what you are saying Nick. If the data calls for 64 grains of H4350 ( starting load), I can start with 64 Grains of Imr -4350? Is that correct?
I am working up some different loads for my 270 Wby. Using 140 Grain Nosler Accubonds.
Thanks, I am just going to stick with the manuals recommendations.Rugerfan, in my experience, H4350 seems to be a little lower in pressure and slower than IMR4350.
You could substitute H4350 for IMR4350 by charge weight but not go the other way.
I played with a lot of H4350 and IMR4350 trying to find the load that my rifles preferred and from what I can see from my notes, equal weight loads of IMR4350 produced 40-70 fps more velocity than similar weights of H4350. It made little difference in accuracy for my .375 H&H but my 30-06 really shot better with the IMR4350.
