Re: powder burn rate
Jody, Just use the two lists as a very very rough guide, as in my testing with the powder lots I have used, I get very different results with some of the powders listed. I am pushed for time at the moment, but will illustrate later with some examples.
Also, if you look closely at those 2 lists some powders vary dramatically. Vihtavouri N170 is a glaring example, being listed as faster burning than H1000 in one, and slower burning than H870 in the other. Regards, Brian.
