Can you interchange these powders? For example if a load called for 55.0 grains of IMR 4831, could you use 55.0 grains of H 4831 instead?

Nope. Even though they are owned by Hodgdon, IMR powders do have different burn rates. Go to [link]http://www.hodgdon.com[/link] for more information.

And that bears repeating.....NO.....don't interchange the numbers and data!!! Only use IMR data for IMR powders and H- data for H- powders!!!!

And I am going to repeat it once more, for no other reason than I got time on my hands.

How does one more time sound?


NO!!

IMR 4831 is closer to H4350 than H4831.

Definately NO!! I even use H4350 and i also Use the IMR4350. I get exact same performance with the IMR and use less Grains. Groups and everything Are the same with both powders, But the Amount used is different.

I Use 40g Of H4350

And 38g of IMR4350

I NEVER Interchange Info. I start with the min recomended charge, and work up. For hunting rounds(i sight in a month before), I will hot load a grain or 2 past Max.

Enough of the rant, The answer to the question is still NO!!

That's a big NEGATIVE. Never interchange powders, use only the powder the data calls for. I, for one, am surprised that the different powder makers use the same nuber designations for their respective powders, even though they are very different. Seems like a liability issue to me in out sue happy country.

I like the current trend toward naming powders instead of numbering them (i.e. Varget, Big Game, etc...), or at least going with simple sequential numbering systems based on relative burn rate (i.e. RL-19, RL-22, N-110 & N-120, etc...).

If there is any rhyme or reason to Hodgdon, AA, or IMR's numbering system, I'd sure like to know what it is.
