Greetings! Ive started making my own BP. It works well! However, I am new to loading BP cartridges, and I get conflicting information regarding weight and volume. I have been loading each case with 50 grains by weight in my .45-70 1884 Trapdoor with a Lee 405 Grain HB boolit. I'm not looking to discuss my load data, as its irrelevant for this discussion. What I need to know, is why are people telling me to load by volume??? I have been weighing out 50 grains, and not using volume. My understanding is that a volume measure simple averages out what would be an accurate AVERAGE WEIGHT. Is this wrong? Why wouldn't weight be more accurate than volume?
