Cartridge load development was once a simpler task that it is today, mainly because the often confusing range of components did not exist. Projectiles were either pointed or round-nosed with a lead tip, the range of powders was minimal and the same applied to primers.
Today the reloader is confronted with a huge range of powders, primers and projectiles, the combinations of which would give a computer a headache trying to work out the best combination for the task at hand. We could throw brass, dies and various reloading manuals into the mix to further complicate the issue. So where do you start to sort out the wheat from the chaff?
