Thread: Old Powder Burn Rate Chart

Shame these charts don't have an actual figure of burn rate next to each powder. Powders listed adjacent to each other could still be quite different and you'd be better able to pick which of the two adjacent powders you'll use reloading data for.

Yes, as pointed out above, Burn Rate comparisons don't equate to Load Data comparisons. What the chart does help for is to find a powder that MIGHT give similar performance and then you go get specific published data for that powder. Of course, despite all warnings not to, people use it to jump from a known powder to an unknown, including me, but that is a highly risky business and results are on your own head.
