Well, as a newbie, I was wondering what the most efficient approach is for sorting through all of the different combinations that a guy could try while searching for that optimal load that my rifle likes most. The way I see it, there are at least 5 variables. Bullet Brand Bullet Weight Powder Brand Powder Weight Brass brand If you add up all of othe possible combinations that I could come up with, that's a LOT of shooting. I'm shoot Do you stick with one specific bullet and weight, and cycle through different brands of powder and different powder amounts . . . or do you stick with one powder brand and cycle through different bullets at one measure of powder. . . . or do you just pick what you think is a good bullet and try different powder brands and measurements . . . If I went through all of the different loading permutations that are available . . . I'd need 3 different barrels just to get through them all with 5 shot groups. Any help would be appreciated. I'm leaning towards Retumbo and Berger 180's or Swift Scirocco II 150's. I'd prefer the heaviest bullet that I can get accuracy with, as I'm hunting Elk and Mulies.
