I say one of the better ones you're going to find is on the URL below.

Steve's Pages

Look under Table 3

If you have Adobe Reader on your computer (most people do), and you can read PDF files, Vihtavuori's reloading manual has a burn rate chart on page 2. (I have no idea whether it is correct or not)...

P.S. If you don't have Adobe Reader, you can download it for free from the Web.

GSP7 you could export them into excel. Then create another document and put them in any order you wanted.

There are a number of "relative burning rate" charts available from various places, mostly for free. All of them are fully worth the money you pay.

As for Steve's chart, I like it! I find it very easy to understand and locate powders of similar burn rates.

Which it might be in some case sizes and when applied to certain relative bullet weights. That's what makes "relative burning rate" charts so approximate. For example, many of them list H-335 as slower than BL-C2, even though as case size increases the maximum charge of H-335 falls several grains below BL-C2. In other instances, they're just plain wrong, like the one I saw recently that put RL-7 faster than IMR 4227.

As I state at the top of my chart...

"Approximate Powder Burning Rates From Fastest to Slowest
Now, before you even begin to look at this table, please note CAREFULLY the word "APPROXIMATE"!

It seems as if I have spent the last 45 years compiling data from all reloading component manufacturers who have seen fit to release THEIR "relative powder burning rates".

These guys can't agree on anything!

As a matter of fact, even the same manufacturer will change their data on a year-by-year-basis. So if they don't know what the hell they are doing, how should I?

The variation in "relative burning rates" varies not only by manufacturer, year and which way the wind is blowing, but also by the capacity of the case you are loading that powder in, the type of primer you are using, and the weight of bullet which is sitting on top of that primer and powder.

Not only that, but it also depends on how much powder you are loading.

Now add all that together, and then confuse the matter even more because each lot number of the same powder, from the same manufacturer, may have a different burning rate with up to a +/-5% tolerance!"

Steve , Like your color codeing for simular rate powders.

I wanted several references for comparison.

Im playing with a 3006 and H4350/180gr accubond. Got a good load worked up.

Now Im going to play with some R19. I study nosler,speer manuals, and Hodgden/alliant charts to get an Idea of safe powder weights to start with, with R19. Looks like R19 is abit more slow than h4350. I was thinking they were about the same. Though they might be.
