Hodgdon's website has cowboy loads for Clays. It's a great powder for reduced loads because it isn't position sensitive and works well with charges that aren't up against the primer. A pound of Clays MAY load up to 2000 rounds of 38 SPECIAL, so you would be set for a while with 38 S&W, unless you start loading other cartridges like 44 special, 45 Colt, 44 Russian, 32-20 WCF, 38-40, 44-40 and the list goes on and on! Have fun, Ivan
