I've been researching the importance of load density when reloading and I believe I understand the importance of why it should be considered when reloading and how it can affect your results in terms of accuracy and velocity. I also feel I have a reasonable understanding of the factors that effect a loads density such as powder burn rates, type of powder - fine vs course powder grains and the like. What I can't seem to find is if there a density threshold at which you start seeing deminishing results. Is below 80% too much? Is over 90% high enough not to be concerned anymore? What is too low? Thanks.
