I ran across these two sites on another forum and thought they were interesting. They show results from various ammunition in different barrel lengths. http://www.brassfetcher.com/45ACP.html http://www.ballisticsbytheinch.com/results.html If anyone has other websites to share with this type of info, I'd be interested in checking them out.
What cartridges are you interested in? I have a whole folder devoted to terminal ballistice for hunting and defence. http://www.m4carbine.net/forumdisplay.php?f=91
