With powder, you have to settle on a charge weight but, just as importantly, you need to charge each cartridge case with the same amount of powder. The only way to do this is by measuring the powder charge. When black powder was the only powder shooters used, it was most often measured by volume. Due to the burning characteristics of modern smokeless powders, it should be measured by weight. However, if done carefully, it can also be measured by volume.
