guys my 308 is finally ready to pick up from smith and I'm ready to start working on load development. I have Luna brass, 152 grain Hammer Hunters, F215 primers but I'm not sure which powder to start with. It must me a temperature stable powder. Choices from what I have on hand....varget, H4350, Retumbo, H4895, or H4831sc. I'd like to get to 3,000 fps. Leaning towards varget but I read an old post of someone using Retumbo but they never came back to post results. I'm thinking Retumbo will be too slow. I have a 20" barrel. So what have you had good luck with or recommend.
