Handloader #317 and has a fairly comprehensive burn rate chart on p. 8, courtesy of WesternPowders.com I've attached it to this post as a PDF.

Thanks Maven. My complaint is that looking at it on my phone I can't see all the right side columns. And can't move the image sideways to view the right side columns.

Man, am I getting old. Not only have I not heard of some of those powders, I've never even heard of some of the makers! I'm "SITE", Stuck In The Eighties. I remember when ANY Norma powder was exotic. Life has passed me by! :)

I agree Bret. I have quite a few powders in my inventory, but they are all the “old” standards.

Have you noticed when Handloader covers a cartridge they seldom include any of these old powders.

I guess I'm stuck in the past as well, but I think having such a chart at hand is a good way to see how the new propellants stack up against the old. E.g., I picked up a few pounds of Lil Gun last year at a good price and thanks to Hand Loader have a much clearer idea of its relative burning rate and use.

I stopped subscribing to Handloader a good 10-12 years back when the editor threw one of his hissy fits and got me totally PO'd. I might buy 1 copy every 2-3 years if I see it in a rack and there's a particularly interesting article in it. But yeah, I saw the trend in promoting only what was new and fancy many years back. Making the advertisers happy is what keeps a mag going.

they done that to string the readers along into chasing the next 1/2" group in their new rifle they read about last month.

that chart seems a little off to me on some of the powders positions when looked at from left to right, but is spot on as far as each company's relative rate.
I have a much older version of this chart and it's shifted a little closer to what I have seen on the bench.

Doesn't work properly for me either....the right side stops at the ADI powders and won't scroll over.........

Unless I'm reading this wrong, it says HP38/W231 actually burns faster than AA#2? This seems backwards compared to the other chart I've been using.

Could it just be that in certain cartridges or at certain pressures, AA#2 is faster, and in other situations it's slower?

I don't know how new that chart is, for instance it doesn't list Vihtavuori N32C, been around for a while and popular with CAS shooters amongst others.

I think it's missing some Vectan powders too.

I think 32C is listed as Tin Star over here, or was,,, I haven't seen it in a while.

Yes they labelled it Tin Star a few years ago to compete in the CAS market.

I sell a lot of it, I think N320 is a far better performer but then I have no need for bulked up powders.

not at that burn speed.
it wouldn't break my heart for 25grs of something around the 4198 area to fill a 308 case though.
