I have an old one that does not include newer rounds. But for my .204 Rugers I use chambering specific data and do just fine. There is plenty of good loading data available...check out 204Ruger.com and click on loading data. It is material taken directly from Hornady/Sierra/others right from their books.
Powders I have found that work very well include WW748, RL-15, RL10x, H322 but there are plenty of others. My .204s don't seem to be to picky about such things.
PS when you ask for specific loading data online you set yourself up for some serious potential issues. Not the least of which include typos, number transposing, misguided handloaders way overloading, errors of every imaginable component. Go to published info to confirm anything you read anywhere online.
