Besides many of the powders I've seen mentioned here already, I also really like Accurate #9 for full power 357 and 44 Mag loads. Less flash from it as compared to H110. I've also been shooting a lot of Longshot and really like it in 357, 44 Mag and also it does well for me in 9MM. I used to shoot a lot of Blue Dot in my 357's but it doesn't meter as well as some of my newer choices such as Longshot.
