Shortmag3, what powders do you have available to you? I know lots of guys are using worked up loads with Retumbo, RL-25, and H-1000. Those seem to be the most popular with Retumbo getting most mention. I have used H-1000 worked up to Noslers max and it topped out at 3050-3060. I've heard, and Nosler printed that Retumbo will go to something like 3187 but have also heard that the ES and SD open up and are not near as good as they are with H-1000.
