As we know St. Marks in Florida has manufactured ball or spherical powders for both Winchester and Hodgdon. The list includes WW780, WW785, WMR, W760, Supreme780, H450, H414, and others.
It has been admitted by Hodgdon that H414 is W760. Anyone know for sure that any of the others are identical to each other? Thanks.

Many years ago, say in the 1970's, I remember reading that W780 and H450 were the same powder. I shot a fair amount of both back then, and they performed pretty much the same, about like a ball version of surplus H4831.
Now I'm really reaching on this, but when WMR was first introduced, I think some gun scribe wrote that it was re-packaged W785. But I am old and senile these days, so others might chime in before you take that as gospel.
I was hoarding when hoarding wasn't cool.

HP-38 and W231 are the same according to the Hodgon website and a release from the maker. However if you look at some reloading data you get two different loads for each powder. I don't know if they are using recycled old data before they got under one corporate umbrella or differences in lots.
Up until last year on Hodgons website there were differences in load data. Now it's all exactly the same grain for grain across the board between the two powders.
One is usually $1 cheaper per pound as well.
If you look at the MSDS for both powders they list each as AKA OBP231.

WAP and Silhouette are the same powder.

I dont dispute the fact that H414 and W760 are the same powder now, but I have old lot's of both and they are not the same. When did this change happen???

Different lots will be - wait for it - different. That's why data varies. The powders are identical within allowable variations. Canister powders (IIRC) must test within 5% to be sold at retail and most manufacturers try to hold that to no more than 3%. That still accounts for some small performance differences.
The current list of identical H and W powders is:
HP38 = W231
HS6 = W540
HS7 = W571
H110 = W296
H414 = W760
Note that H335 is NOT W748, as some believe.
