Powder equivalent charts?

[Paddy]

Is there any charts that reveal what the rebranded names of ADI powders are? I just found out that my international clays is actually ADI AS50N. It would be useful.

I can't vouch for its accuracy.

http://www.adi-powders.com.au/handloaders/equivalents.asp ADI - Hodgdon. Maybe this?

Look at the MSDS http://www.hodgdon.com/msds.html :banghead:

Veeeery interesting. So, ADI has it that w748 and H335 are identical, is this chart safe to completely switch and swap data? Red dot and clays are the same? (Without the dots I'm assuming)

For Burning rate comparison only

http://www.adi-powders.com.au/handloaders/equivalents.asp w748 and H335 are NOT identical.

NOTE: These tables are only approximate, showing equivalent values within about 5%.

Actual burning rates can vary depending on the calibre, weapon, loading components and practices, as well as from powder lot to powder lot. As a consequence it must be understood that Australian Munitions cannot accept any responsibility for the use of this information in any way.

How can they claim "equivalent" and within 5% in the same breath?

Seems reasonable to me.

Since physical properties are never perfectly exact, even from lot to lot of the same powder...
What sort of error term would you require for 'equivalent'?

 

[Paddy]

I guess to me equivalent means interchangeable. It's odd to me that this word would come from the mfg if its not in fact interchangeable. Still good to know I suppose!

ADI is not the manufacturer of either Win 748 or H335 ... St Marks Powder Company in Florida is ...
