I’ve run across this site a couple of times in the past, but not recently. It seems to have been inactive for awhile, but is still up and running. This is an index of links to articles, a few of them having to do with ammunition. The most interesting is the original forensic analysis of ammunition used in the 1929 St. Valentine’s Day massacre in Chicago. There is another on sounds of bullets passing nearby, with sound spectrums and recordings.
That is a very interesting website, fascinating.
