[QUOTE="WildcatB, post: 454077, member: 10379"] I read the exact same paper. That's how I plan on measuring our bullets BC's. In fact, I nudged a kid at school into doing this for his science project. Audacity is free and most people already have a laptop. I'd just use the time of flight and JBM's Ballistic Coefficient (Time) calculator [URL="http://www.jbmballistics.com/cgi-bin/jbmbct-5.1.cgi"]HERE [/URL]to get the BC's from the time of flight data from the sound card. We'll see how it matches with my drop data. I'm also going to use Adobe's Sound Booth to see if the time measurements differ. [/QUOTE]
