Or, are the charge weight and burn rate completely independent?
I suspect they are completely independent as I see load data for a random cartridge that shows 49.0g as a starter load for H4831 and 43.2g for N160 both of which are adjacent in the table. As such, the starter load for H4831sc is well above the max load for N160.
I like the list for what it is. But, it's not load data.
Charge rate and burn rate are
completely independant issues. Burn rate charts are useful tools for comparing powders when trying to decide whether one will be useful in a given application, but as has been stated, you still need some reference source to establish a load. That's where lab developed, empirically tested data from the manufacturers comes in. The analogy here between H4831 and our own N160 is a good one. Very similar in burning rate, but substantially different in many other regards.
