This site isn't just for people starting out. The Hodgdon website, reloading manuals and other company sites provide information for all reloaders, regardless of experience level. . Good reloaders do not guess. They research first.
John:
Do you also try to look for one with close to maximum case fill (discounting the compressed load data)? Do you find those loads that show 95-99% density the most consistent?
I suspect John looks for 90% plus case fill for almost all rifle loads. They perform the best for regular hunting and target cartridges. The only exceptions can be cast or low power loads for small game.
