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!

So there you have it guys ...

Again, these are approximate burning rates.
Powders listed in the same color blocks are similar, but in no way identical.
DO NOT INTERCHANGE POWDERS WITHOUT RE-WORKING YOUR LOADS!
