The mother of all burn rate charts...

Stumbled across and thought I would leave it here. Not perfect but maybe a good resource? 526 powders listed...

That’s the first time I’ve seen Retumbo listed slower than RL26 and IMR7977

That’s a good point. Retumbo is also listed as faster than ADI AR2225 and those are the same powder from what I am lead to believe.... Mind you Retumbo is listed at 494 and AR2225 is 495 (And reloader 26 is 496) so a very small difference incrementally but a bit of a head scratcher. Maybe not such a good list then? I may well be an idiot for posting it. If there is an issue I am more that happy to be called on it. I am neither Gods gift to reloading nor well versed in burn rates. Just wanted to pass along what looked looked liked a solid compendium. I’ll pull it down in a heart beat if it is bad data.

Idk why I though this was for time fuse.

I wasn’t saying it was bad or good nor calling you on anything. All burn rate charts have some degree of variation. It’s just the first time I’ve seen one with that particular order. I do like the number of powders and brands listed

The chart shows AR Comp at a burn rate near IMR 4320. From my experience with it, it's closer to IMR 3031 / 8208 XBR. I'm shooting lots from 2013. I bought 2-8# kegs back then. I read where Alliant tweaked AR Comp a little sometime around 2015, but I wouldn't think they would have slowed it down that much, that would have changed the reloading data a lot.

Thanks for helping me finally justify my 4K 40 inch monitor.

None of the ADI made Hodgdon powders line up despite being identical. 8208 and Varget being two more examples.

I think you guys are taking it a bit too literal. There's only one powder per line - so even with identical powders of differing branding, one has to be listed first.

Nice, thanks!
