Just saw this today. You have to take the chart with a grain of salt, but was interested to see that BE-86 is now listed. Hodgdon has it just after VV340.
Piqued my interest because WSF, VV340 and BE-86 are 3 of my favorite powders for 9mm loads and official data for BE-86 is somewhat lacking. Some unofficial sources had it between Unique and Universal but in my experience it performs very closely with WSF and VV340 with similar charge weights. Please not that I said SIMILAR and not the same.

Thanks for that...I like to compare different charts and the color coding on the Hodgdon chart helps.

Although useful, the problem with these type charts is that they seem to present the powder as equally spaced in a sequential order, when they are not. Some ranked as numerically close might be identical equivalents. And then the spacing is not as equal as one might be led to think. That is, the increment between 35 and 36, may not be the same as between 39 and 40.
For that reason I prefer a relative chart, like: https://cdn.poptemplate.com/Image/728/powder-burn-rate-chart-3.jpg
But still it's good that BE-86 has finally been included.

Where is 2400?

Wobbly in that chart you provided the link for it lists a Winchester powder 571. do the mean 572?
Never would have noticed it if I hadn't been looking for a powder with a burn rate close to Blue Dot.
Just curious.

Not my chart, so I have no idea. But it does look like the chart Vit used to have.

Wobbly, just looked at another source for powder burn rates and saw a Winchester 571 and a 572. Oh well.
Edited to add - just looked at several powder burn rate charts on the internet. Some only list 571, some ony list 572, some don't list either.
Unkown to the people making the charts? Not common enough to test? Mistakes when the number was typed in? Who knows.
The ones that do show 572 show it with Blue Dot, right before or side by side.

It may be a Winchester powder only sold in Europe ??

I prefer the powder burn chart that western powder had. The different manufacturers were arranged in columns. It made things easy, I.https://ramshot.com/wp-content/uploads/2010/12/burn_rates.pdf

I've ordered some of the 572.
Supposed to be (I read somewhere) what Winchester uses for the 124 grain FMJ NATO ammo that my M&Ps seem to shoot better than anything else.
I already went through a round of Unique, Blue Dot, BE86(?) and AA#7 and didn't get anything acceptable vs. the Winchester NATO ammo using 124 grain hollow points. Figured I'd try the 572 and see if it'll do the same thing with the hollow points it does with the FMJ.
Burn rate is supposed to be about the same as Blue Dot but uses a little less powder to get there.
We'll see how it works out.
