Relative Burn Rate Charts, which is the most accurate and up to date? I have seen several different burn rate charts from Hodgdon, Hornady, Nosler Handloader.com along with a few others and none of them are inline with one another. Some are close in some aspects and way far apart in others. There are a lot of new powders out on the market these days too, I would like to know were they fall in the scope of things. I'm not trying to reinvent the wheel, but there are some new spokes that could help the wheel go round better. Thanks for any input.
