Haven't seen this in awhile. Maybe some new folks might find it interesting.

Input what you know, hit search, and look at the zoomed powder picture.

Just used it to verify what IMR SR4759 looked like.

Cool info 762

If you go to the bottom of the list you can see what the original cans looked like :)

Good link-- I've been using this site a lot over the years. By looking at the photos you can get a pretty good idea about which powders will meter well and which won't. If you happen to know chemistry (I'm a retired Chemical Engineer) you can also tell from the analysis data, together with the size and shape of the particles, how two supposedly similar burn rate powders are really the same or different. Very useful information.

Thanks 762!! I bought a large bunch of powder in partial cans and was needing to make sure the powder in the cans matched the label. There are about 11 powders that I am not familiar with and this will help me identify these and use or turn into fertilizer. Learn something new on this site almost daily.
