In my experience of reloading ( 25+ years ) I have always tried to use a powder that filled the case as much as possible. This accomplishes two thing. 1) Reduced risk of a double charge. A double charge would over flow the case and tip off of an error. 2) Reduced "dead" space in the case. The less "dead" space translates into more energy. The burning powder has less room to expand before pushing the projectile. Consult the specs on the case and see how many grains of water the case is designed to hold and select the powder accordingly. Ralph
