Trust but verify the honeyguide
Anybody know the standard for measuring burn rate?
My Anchor is holding fast!
The method I'm aware of uses a closed, thermodynamic testing chamber. Of course it yields BTU data for any material burned inside and can measure the relative rate of burn amongst the powders being tested. Relative being the operative concept within the unlimited expansion ratio variables.

It would be nice to beable to down load this chart. There are many brands that are not readily available and don't desrve to be on any list I use. In this format the columns of worthless brands could be deleted.

You can download, save and manipulate the cahrt if you have Microsoft Excel.
I highlighted the entire chart. Right clicked, selected 'copy', went to my open excel spreadsheet, highlighted 1 row, selected 'paste'. Put it in, got the warning 'cells aren't ...' ignored that.
Saved it and started slashing what I didn't need. Adjusted the row sizes to fit my needs, added a column for 'surplus powders' .... ad naseum. When done re-saved under a differnet name so I have an 'original' if I need it.
That works if you are using Apache Open Office, too. (AOO is a totally free suite of programs completely compatible with - but better than - Microsoft stuff.)
I like this chart for my uses. They have a .pdf file which is more to my liking.

Beware of man who types much, but says nothing.
I like that one but it too is incomplete. I see there are no surplus powders much to my dissapointment.
Just a quick once over and I see in the h-870 win-870 burn rate that AA-8700 is missing. That leads me to believe that under close scrutiney I would discover the absence of others.
Not to belittle the chart as I like it but all seem to fall short of being complete and is why I keep several just as I do with loading manuals to cross reference.
I also see a lack of a few cartridge loads I'd need as in 250-Sav and 416 Rigby. I did note the 458 Lott there and think there are probably more 416 Rigbys than the 416 Rems and 4589 Lotss put together. Just my 'gripey' $0.02.
This burn rate chart is good one http://home.hiwaay.net/~stargate/powder/powder.htm

Nope. it isn't. That one is just another "One through xxx" style where any two adjacent powders can be identical, quite close or pretty far apart in burn rate. Worse, it is forced to put identical powders on different lines (see its listing for W231/HP38, which shows them several steps apart - ludicrous.)

Yes this is a good burn rate chart. The 231/hp38,760/h414,hs6/540,hs7/572 etc is just different lots of same powder tested. Yep a good one, one of the most complete I've found, I likey a lot.

H110 and W296 were not the same powder as they are now. Years ago there was a difference and I'm not sure if you can use the new powder data with the old powder. Not exactly sure but I think the 296 has changed, anyway both are made by the same company made the same just different label. Probably some other powders done the same way, H4198 & IMR4198?
I am trying to find an equal to W785 for my 270 Win. It only shoots well with 785, it hates 4831, 4350 and all the powders every one claim are so great in the 270 Win. According to burn charts W870 is listed on the same line as W785 but cane find no data for it in the 270
