Not sure what type of setup your using but I for one an a tech geek and find this very interesting.

Having said that I'd love to see some period 38 Spl testing. This round has some controversy about if it's been downloaded over the years. Supposedly original 38 Spl, out of a 6 inch barrel, was good for 1000 fps with a 158 gr LRN, hotter then today;s FBI +P load.
