Other Resources BBTI is not the end-all of ballistics testing, just one more component available for the common good. In addition to extensive discussion about ballistics to be found at many gun forums, here are some other great resources pertaining to ballistics testing you should check out. (And if you would like to recommend a site to list here, please send an email.) BrassFetcher: excellent resource, with an emphasis on bullet performance in ballistic gelatin

Acknowledgements We'd like to personally and specifically thank Pat Childs at Fin & Feather in Iowa City, as he not only helped get most of our ammunition and other supplies, he was the brilliant gunsmith who worked with us to make this insane project much more practical. Without his help all of this would have been much more difficult and perhaps impossible. Anyone who uses our data owes him a debt of gratitude. And thanks to our spouses, who were not just tolerant but enthusiastically supportive of this rather nutty project.
