[QUOTE="QuietTexan, post: 2056827, member: 116181"] They come into play for long extruded powders at max case capacity, otherwise they don't do much. The longer drop somehow aligns the cylinders better and fit more kernels into a given case volume, meaning there is less compression. I haven't used a load that requires me to compress an extruded powder, so I don't have or use one. I'm sure there is a very detailed explanation somewhere out there, but the TL;DR version is that the density of randomly packed identically shaped objects is not optimized. Spheres that are randomly packed have a density of 64%, but optimally packed spheres have a density of 74%. The 10% increase in density is entirely related to packing more efficiently.
